Chapter 14 Quiz: Health Misinformation — From Snake Oil to Anti-Vax

Instructions: Answer each question. Click "Show Answer" to reveal the correct response and explanation.

Part I: History and Regulation (Questions 1–5)

Question 1

The Pure Food and Drug Act of 1906 prohibited:

A) The sale of ineffective patent medicines B) All health claims that were not supported by clinical trials C) The misbranding of foods and drugs through inaccurate labeling D) The use of alcohol in patent medicines

Show Answer **Correct Answer: C** The 1906 Act prohibited misbranding — requiring that labels accurately disclose ingredients — but did not require proof of efficacy or prohibit therapeutic claims. A manufacturer could legally sell a product claiming to cure cancer, as long as the label accurately listed what the product contained. This critical limitation meant that fraudulent health claims could continue legally. The more comprehensive restrictions on false therapeutic claims came later, through the FD&C Act of 1938 and subsequent amendments.

Question 2

The Dietary Supplement Health and Education Act (DSHEA, 1994) created what is described in the chapter as a "regulatory gap" because:

A) It required supplements to be approved for safety but not efficacy before marketing B) It exempted dietary supplements from pre-market approval requirements, allowing marketing without proof of safety or efficacy C) It allowed international supplement manufacturers to bypass FDA review D) It removed criminal penalties for fraudulent supplement claims

Show Answer **Correct Answer: B** DSHEA shifted the regulatory burden from manufacturers to the FDA: rather than manufacturers proving safety before marketing, the FDA must now prove a product is unsafe after it is already on the market. Manufacturers may not claim their products treat specific diseases, but may use structure-function claims ("supports immune function") without evidentiary standards. This gap has enabled a multi-billion-dollar industry in products whose health benefits are frequently unsupported by clinical evidence.

Question 3

Short Answer: Explain why the 1937 Elixir Sulfanilamide disaster was not preventable under existing law, and what regulatory reform it precipitated.

Show Answer **Model Answer:** The 1937 Elixir Sulfanilamide disaster killed 107 people when sulfanilamide (a real antibiotic) was dissolved in diethylene glycol (a toxic industrial solvent). Under the 1906 Pure Food and Drug Act, the FDA had no authority to require pre-market safety testing. The product was accurately labeled with its ingredients; the antibiotic itself was not fraudulent. The FDA was therefore powerless to prevent the product from reaching consumers, even though it was lethal. The disaster demonstrated that accurate labeling alone was insufficient to protect public health. It directly precipitated the passage of the Federal Food, Drug, and Cosmetic Act of 1938, which for the first time required manufacturers to demonstrate safety before marketing new drugs.

Question 4

Which of the following most accurately describes the rhetorical function of "testimonials" in patent medicine marketing (and contemporary health misinformation)?

A) They provide rigorous evidence of product efficacy through individual case documentation B) They substitute individual anecdotal cases for population-level clinical evidence, exploiting our tendency to be more persuaded by narrative than statistics C) They comply with regulatory requirements for proof of efficacy D) They represent a form of consumer research that predates modern clinical trials

Show Answer **Correct Answer: B** Testimonials exploit the well-documented tendency of human cognition to be more persuaded by vivid individual narratives than by statistical population data — even when the statistics are more epistemically reliable. A single emotionally compelling account of miraculous recovery is more persuasive to most people than a large epidemiological study showing no benefit. This makes testimonials an extremely effective marketing tool for ineffective products: the product does not need to work for most users; it only needs to have worked for one compelling testimonial subject (or appeared to work, through placebo effect, natural recovery, or selective reporting).

Question 5

The appeals to nature fallacy — the inference that "natural" products are safer or better — is described as psychologically compelling despite being logically flawed. Which of the following best explains its psychological appeal?

A) Research shows that natural products are in fact statistically safer on average B) It connects to broad anxieties about medicalization, technology, and perceived lack of autonomy that are not fully addressed by evidence-based medicine C) Most people lack the scientific education to recognize the fallacy D) The fallacy is promoted by the pharmaceutical industry to discredit natural alternatives

Show Answer **Correct Answer: B** The appeal to nature is psychologically compelling not merely because of scientific illiteracy but because it connects to genuine and understandable concerns: anxiety about the depersonalization of medical care, desire for autonomy in health decisions, distrust of corporate-driven medicine, and attraction to holistic frameworks that treat the person rather than the disease. These are real needs that evidence-based medicine often fails to address. The appeal to nature gains traction partly because of these genuine gaps, not purely because of scientific misinformation.

Part II: Vaccine Hesitancy (Questions 6–11)

Question 6

The WHO's three Cs model of vaccine hesitancy identifies which three drivers?

A) Conspiracy, costs, and communication B) Complacency, convenience, and confidence C) Concern, culture, and credibility D) Compliance, control, and community

Show Answer **Correct Answer: B** The WHO SAGE Working Group's three Cs are: Complacency (low perceived risk of vaccine-preventable disease leading to reduced vaccination urgency), Convenience (physical, logistical, and financial barriers to access), and Confidence (trust in vaccine safety, efficacy, and the health system). Each driver calls for different interventions: complacency calls for risk communication; convenience calls for structural access improvements; confidence calls for trust-building communication.

Question 7

Herd immunity for measles is achieved at approximately 93-95% vaccination coverage. Which of the following best explains why a decline from 95% to 88% coverage is more dangerous than it might initially appear?

A) The 7% decline directly corresponds to a 7% increase in measles cases B) The decline eliminates the herd immunity threshold entirely, potentially exposing all unvaccinated individuals to epidemic risk C) At 88% coverage, vaccinated individuals also lose their protection D) Measles becomes 7% more contagious at lower population coverage rates

Show Answer **Correct Answer: B** The herd immunity threshold creates a non-linear relationship between coverage and epidemic risk. Above the threshold (93-95%), chains of transmission cannot be sustained and even unvaccinated individuals are protected. Below the threshold, the disease can spread through susceptible populations. A decline from 95% to 88% does not merely reduce protection linearly; it removes the threshold entirely, enabling epidemic spread. This explains how relatively small declines in vaccination coverage — as occurred following the Wakefield paper — can enable measles outbreaks.

Question 8

Short Answer: Explain what it means to say that vaccination is not a purely individual health decision, using the herd immunity concept.

Show Answer **Model Answer:** The decision not to vaccinate has consequences beyond the individual who declines vaccination. When vaccination rates fall below the herd immunity threshold, the entire unvaccinated population — including those who cannot be vaccinated for medical reasons (infants too young for vaccination, immunocompromised individuals, people with vaccine allergies) — loses the community protection that high vaccination rates provide. These medically vulnerable individuals are protected by herd immunity and endangered when it breaks down. A person who declines vaccination is therefore making a decision that affects the health of others in their community, particularly those least able to protect themselves. Anti-vaccination advocates typically frame vaccine decisions as purely individual health choices, but the herd immunity concept demonstrates that this framing is incomplete.

Question 9

Research by Johnson et al. (2018) found that patients with resectable cancer who used alternative medicine as primary treatment had a 5.68-fold higher hazard of death compared to patients receiving conventional treatment. This finding is most directly relevant to which of the following claims?

A) Alternative medicine is ineffective for all conditions B) The harm of health misinformation in cancer is primarily direct toxicity of alternative treatments C) A significant portion of health misinformation's mortality effect operates through the opportunity cost of delayed or forgone conventional treatment D) Patients who choose alternative medicine have worse prognosis at diagnosis

Show Answer **Correct Answer: C** The study's key mechanism is opportunity cost: patients who use alternative medicine as primary treatment delay or forgo standard-of-care treatment during which the disease progresses. The harm is not primarily from the toxicity of the alternative treatments (though some cause direct harm) but from the failure to receive treatment known to be effective during a window when treatment can prevent death. This is the mechanism by which health misinformation kills cancer patients: not through direct poison but through the displacement of effective treatment.

Question 10

The motivational interviewing principle of "developing discrepancy" involves:

A) Telling patients that their beliefs are inconsistent with scientific evidence B) Helping patients recognize contradictions between their stated values and the implications of their health decisions C) Identifying contradictions in the misinformation patients believe D) Providing statistical data that contradicts patients' anecdotal evidence

Show Answer **Correct Answer: B** "Developing discrepancy" is an MI technique that works within the patient's own value system rather than imposing external values. For vaccine hesitancy, this might involve exploring a parent's deep concern for their child's health and safety, then gently exploring how declining vaccination relates to that concern — helping the parent recognize that the stated goal (protecting the child) and the hesitant behavior (declining protection against disease) may not be fully aligned. This is different from confrontation; it is a process of helping the person discover their own reasons for change.

Question 11

Short Answer: What is the "asymmetry of claim and refutation" that made the Wakefield false claim particularly difficult to counter, and what does it suggest for health communication strategy?

Show Answer **Model Answer:** The asymmetry refers to the difference in complexity between a false health claim and its accurate refutation. "Vaccines cause autism" is a five-word claim that is simple, memorable, emotionally resonant, and instantly communicable. The accurate refutation requires: explaining that the study involved only twelve children and cannot support causal conclusions; discussing the multiple large-scale epidemiological studies that found no association; explaining the diagnostic expansion that increased autism diagnoses; describing the undisclosed conflicts of interest; and accounting for why the apparent temporal association (vaccination and autism diagnosis both occur in early childhood) is not evidence of causation. The refutation is complex, requires background knowledge, and is far less emotionally resonant. This asymmetry suggests that effective health communication strategy should focus on pre-emptive inoculation rather than post-hoc refutation, and should communicate accurate information in simple, emotionally resonant formats rather than leading with complex technical arguments.

Part III: COVID-19 Infodemic (Questions 12–17)

Question 12

The WHO's term "infodemic" refers to:

A) An epidemic of conspiracy theories about vaccines B) An overabundance of information — both accurate and inaccurate — that makes it difficult for people to find trustworthy guidance during a health crisis C) The deliberate spread of false health information by state actors D) A situation where misinformation about a disease is more widespread than accurate information

Show Answer **Correct Answer: B** The infodemic concept captures a feature of the information environment that goes beyond simple misinformation: the problem is the volume and velocity of information circulation that makes navigation toward accurate information difficult, even for people who are genuinely seeking it. The infodemic is not purely a problem of false information; it is a problem of information overload in which accurate and inaccurate information compete in the same channels, and where the algorithmic infrastructure tends to favor engaging (often emotional or alarming) content regardless of accuracy.

Question 13

The claim that 5G towers caused COVID-19 is false because:

A) 5G networks were not operational in most countries when COVID-19 began B) 5G radio waves are non-ionizing radiation that cannot cause viral infection or significantly affect biological processes in the relevant ways C) COVID-19 spread in countries without 5G networks D) Both B and C

Show Answer **Correct Answer: D** Both biological and epidemiological arguments refute the 5G claim. Biologically, 5G radio waves are non-ionizing radiation — they do not have the energy to break chemical bonds or damage DNA, and they cannot create or transmit viruses. Epidemiologically, COVID-19 spread extensively in countries without 5G networks (numerous low-income countries, rural areas worldwide), which is impossible if 5G were a causative agent. Despite these multiple lines of refutation, the claim motivated real-world arson attacks against cell towers in multiple countries.

Question 14

Short Answer: Why were health authorities' mask guidance changes during COVID-19 damaging to institutional credibility, even though the changes reflected genuine evolving evidence?

Show Answer **Model Answer:** Early in the COVID-19 pandemic, health authorities (including the WHO and CDC) stated that masks were not recommended for general public use. This guidance was later reversed when evidence accumulated that masks reduced transmission. The reversal was scientifically appropriate — guidelines should change as evidence changes — but it was communicatively damaging for several reasons. First, the initial no-mask recommendation was partly motivated by supply concerns (conserving masks for healthcare workers) rather than purely by the evidence, which meant the guidance was not fully honest from the start. Second, the reversal occurred without adequate explanation of why the earlier recommendation was made or why it changed, leaving many people concluding that authorities had simply been wrong. Third, it provided ready ammunition for anti-vaccination advocates who used it as evidence that health authorities could not be trusted. The lesson is that communicating uncertainty honestly from the start — "we don't yet know the answer, here's what we do know" — is more durable for credibility than overconfident messaging that must be reversed.

Question 15

The hydroxychloroquine promotion episode is most analogous to which historical pattern?

A) The COINTELPRO conspiracy (a real conspiracy correctly identified) B) The patent medicine era (extravagant claims for an unproven treatment, amplified by media, without adequate clinical evidence) C) The Tuskegee study (deliberate withholding of treatment) D) The tobacco industry's suppression of cancer research

Show Answer **Correct Answer: B** The hydroxychloroquine episode followed the classic patent medicine pattern: a treatment with some preliminary evidence and theoretical rationale (it had anti-viral properties in cell cultures) was promoted with certainty that vastly exceeded the evidence, amplified by powerful media figures and political leaders, to a desperately hopeful public. The subsequent randomized controlled trials, which are the appropriate standard for establishing efficacy, found no benefit. The analogy to patent medicine is not that hydroxychloroquine was fraudulently invented (it is a real drug with real uses), but that the certainty of promotion was dramatically out of proportion to the quality of evidence.

Question 16

Research has documented deaths associated with COVID-19 misinformation through which of the following mechanisms?

A) Ingestion of promoted miracle cures (bleach, high-dose chloroquine) B) Delayed presentation to medical care due to false reassurance from misinformation C) Reduced vaccination leading to preventable COVID-19 deaths D) All of the above

Show Answer **Correct Answer: D** All three mechanisms have been documented: direct ingestion deaths from misinformation-promoted "cures" (chloroquine toxicity, bleach ingestion); delayed presentation deaths from false reassurance (false claims that the disease was not dangerous, that natural immunity was sufficient); and vaccination-related deaths from misinformation-driven hesitancy reducing COVID-19 vaccination rates below what could have been achieved. The total mortality attributable to COVID-19 misinformation through all these mechanisms is difficult to estimate precisely but is substantial.

Question 17

Short Answer: The Disinformation Dozen study found that 12 individuals were responsible for 65% of anti-vaccination content shared on Facebook and Twitter. What are the policy implications of this finding?

Show Answer **Model Answer:** The concentration finding has several policy implications. First, it suggests that targeted action against a small number of high-reach individuals could achieve disproportionate reductions in misinformation volume — deplatforming twelve accounts might reduce anti-vaccination content by 65%, a highly efficient use of moderation resources. Second, it supports the case for platform action against specific, identifiable individuals rather than broad content-level removal, which risks overblocking legitimate discussion. Third, it raises due process questions about the power of platforms to effectively remove influential voices from public discourse by deplatforming a small number of individuals. Fourth, it suggests that the supply of health misinformation is not primarily a grassroots phenomenon but is driven by a small number of influential producers with specific financial or ideological motivations — which has implications for legal and regulatory approaches targeting the supply side of misinformation production.

Part IV: Alternative Medicine and Cancer Misinformation (Questions 18–22)

Question 18

Edzard Ernst's approach to alternative medicine claims recommends evaluating them on a spectrum from "plausible but unproven" to "implausible" to "irrational." Homeopathy is typically categorized as:

A) Plausible but unproven, because some clinical trials show modest effects B) Implausible, because the proposed mechanisms require rejecting established chemistry and physics C) Irrational, because it has no theoretical basis whatsoever D) Plausible, because many patients report benefit from homeopathic treatment

Show Answer **Correct Answer: B** Homeopathy is categorized as implausible because its core mechanism — that water "remembers" the properties of substances dissolved in it at dilutions so extreme that no molecules of the original substance remain — contradicts established chemistry and physics. The most extreme homeopathic dilutions (30C) involve diluting a substance to one part in 10^60 — far beyond the point where any molecule of the original substance remains in the solution. The clinical trial evidence, when aggregated in systematic reviews, does not show effects beyond placebo, consistent with the implausibility assessment. Patient-reported benefit is real but is explicable by placebo effects, natural recovery, regression to the mean, and the therapeutic value of the extended consultation typical in homeopathic practice.

Question 19

Short Answer: What is the "opportunity cost" mechanism by which cancer misinformation causes harm, even when the alternative treatments themselves are not directly toxic?

Show Answer **Model Answer:** Opportunity cost harm occurs when patients pursuing alternative cancer treatments delay or forgo standard-of-care treatment during which the cancer progresses. Most solid tumors have treatment windows — periods during which they are treatable with curative intent — that close as the tumor grows, spreads, or acquires drug resistance. A patient who spends six months pursuing an ineffective alternative treatment may have moved from early-stage to late-stage disease during that period, with a dramatic reduction in survival probability. The harm is not from the alternative treatment itself but from what was not done during the treatment period. This is the mechanism behind the 5.68-fold mortality hazard documented by Johnson et al. — it is the displacement of effective treatment, not the direct toxicity of alternatives.

Question 20

A supplement manufacturer claims their product "supports healthy immune function" on the product label. Under DSHEA, this claim is:

A) Illegal unless supported by clinical trial data B) Legal as a structure-function claim, provided the product includes a disclaimer that it has not been evaluated by the FDA C) Legal without restriction, since immune function is not a specific disease D) Regulated the same way as drug efficacy claims

Show Answer **Correct Answer: B** DSHEA permits structure-function claims — statements about how a product affects the body's structure or function — without requiring evidentiary standards, provided the label includes the disclaimer: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." The disclaimer is legally required but is typically printed in small type and has limited consumer impact. If the manufacturer claimed the product "prevents infection" or "treats immunodeficiency," those would be drug claims requiring FDA approval.

Question 21

Which of the following most accurately characterizes the challenge of "terminal illness" exploitation by alternative cancer cure purveyors?

A) Terminal patients are cognitively impaired by their illness and cannot evaluate evidence reliably B) Terminal illness creates conditions where the alternative cure provider is immune from disproof, since neither survival nor death definitively tests the treatment's efficacy C) Terminal patients are more susceptible to exploitation because they have more money to spend D) The regulatory framework for terminal illness is uniquely permissive compared to other cancer stages

Show Answer **Correct Answer: B** The analytical point is that terminal illness creates conditions of near-unfalsifiability for alternative cure claims. If the patient dies, the death can be attributed to the severity of the original illness or to prior conventional treatment; if the patient lives longer than expected (as some do, due to natural variation in disease progression), the survival is credited to the alternative treatment. Neither outcome definitively tests the treatment. This structural feature — the treatment cannot be disproven by individual outcomes — is what makes terminal illness exploitation particularly persistent despite the clear evidence of harm.

Question 22

Short Answer: Why is acknowledging uncertainty honestly a more effective long-term trust-building strategy for health authorities than projecting false confidence?

Show Answer **Model Answer:** When health authorities project confidence they do not have, they face two negative outcomes when that confidence is inevitably challenged by evolving evidence: a credibility loss from the reversal itself, and the provision of ammunition to misinformation advocates who use the reversal as evidence of authority unreliability. Honest acknowledgment of uncertainty, by contrast, communicates scientific integrity — the recognition that science is an ongoing process of refining understanding rather than a fixed body of certain truths. Research on trust shows that honesty about limitations (benevolence and integrity signals) is more durable for trust than competence claims that may not be fully warranted. Audiences who are prepared for uncertainty can process updated guidance without experiencing betrayal; audiences who were promised certainty experience revisions as broken promises. COVID-19 mask guidance changes illustrate the cost of the alternative strategy.

Part V: Integration and Application (Questions 23–27)

Question 23

The chapter draws a parallel between nineteenth-century patent medicine marketing techniques and contemporary health misinformation. Which of the following is the most important implication of this historical continuity?

A) Health misinformation is an inevitable feature of free markets and should not be regulated B) The psychological vulnerabilities that make people susceptible to health misinformation are stable features of human cognition, not products of contemporary media environments C) Contemporary health misinformation is less sophisticated than its historical predecessors D) Regulatory solutions that worked in the twentieth century will be equally effective in the digital age

Show Answer **Correct Answer: B** The historical continuity — the fact that the same rhetorical techniques (testimonials, appeal to nature, conspiracy framing, pseudoscientific language) appear across more than a century of regulatory evolution — suggests that these techniques target stable psychological vulnerabilities: hope in the face of illness, distrust of powerful institutions, desire for autonomy, susceptibility to narrative over statistics. These are not bugs in human cognition created by social media; they are stable features that health misinformation exploits. This implies that purely regulatory approaches — which may reduce some forms of health misinformation — cannot eliminate it, because the demand-side vulnerabilities it serves are not created by supply-side factors.

Question 24

Short Answer: Describe the "narrative asymmetry" that makes health misinformation difficult to counter through fact-checking alone, and explain what approaches the research suggests are more effective.

Show Answer **Model Answer:** Narrative asymmetry refers to the difference in communicative efficiency between false health claims and their accurate refutations. False health claims are typically simple, emotionally resonant, and easily remembered: "vaccines cause autism," "5G causes COVID," "natural immunity is better." Accurate refutations typically require discussing epidemiological methodology, explaining why temporal associations do not imply causation, presenting statistical evidence from large clinical trials, and addressing mechanistic implausibility — all of which require cognitive engagement and background knowledge that many audiences lack or are unwilling to invest. This asymmetry means that fact-checking — presenting the accurate facts after the false claim has been encountered — is relatively ineffective. More effective approaches include: inoculation/prebunking (building resistance before exposure); making accurate information emotionally engaging through narrative framing; targeting messengers who are already trusted within the relevant community; and addressing the psychological needs (certainty, autonomy, community) that make false claims appealing.

Question 25

A public health researcher conducts a study and finds that motivational interviewing is more effective than standard information provision at increasing HPV vaccination rates among hesitant parents. What is the most theoretically coherent explanation for this finding?

A) Information provision conveys incorrect information that motivational interviewing corrects B) Motivational interviewing takes more time, and the additional consultation time itself improves vaccination rates C) Vaccine hesitancy is maintained by psychological and identity factors that information provision cannot address, while motivational interviewing engages with the believer's own values and motivations for change D) Motivational interviewing is more effective because it uses more authoritative language

Show Answer **Correct Answer: C** The theoretical explanation for MI's superiority over information provision is that vaccine hesitancy is not primarily an information deficit problem. Hesitant parents often have access to accurate information; their hesitancy reflects psychological needs (autonomy, distrust of authority, social identity) and specific concerns that information alone cannot address. MI works because it meets people where they are, respects their autonomy, elicits their own reasons for change, and engages with the specific concerns that are maintaining their hesitancy. Information provision, by contrast, treats hesitancy as ignorance to be corrected, which can activate reactance (resistance to perceived threats to autonomy) and deepen rather than reduce hesitancy.

Question 26

Short Answer: How does the historical legacy of the Tuskegee study continue to affect contemporary vaccine hesitancy, and what implications does this have for vaccine communication strategies targeting Black communities?

Show Answer **Model Answer:** The Tuskegee study (1932-1972) represents a documented case of deliberate deception and withholding of treatment from Black men by U.S. public health officials. Research has consistently found that awareness of the Tuskegee study predicts lower medical trust and higher vaccine hesitancy among Black Americans. This elevated distrust is not a cognitive deficiency or misinformation-driven irrationality — it is a rational response calibrated to documented historical evidence of government medical malfeasance. This has important implications for communication strategy. First, dismissing or pathologizing Black vaccine hesitancy as irrational misinformation ignores its rational basis and is likely to increase resistance. Second, institutional authority figures (government health agencies, major medical centers) may be particularly ineffective as messengers for Black communities with high Tuskegee awareness, because the credibility gap is real. More effective approaches include: deploying trusted community messengers (Black primary care physicians, community leaders, faith leaders); explicitly acknowledging the Tuskegee history rather than ignoring it; demonstrating accountability and commitment to community interests through concrete actions, not just messaging.

Question 27

Which of the following best represents the appropriate overall conclusion from Chapter 14's analysis of health misinformation?

A) Health misinformation is primarily a problem of scientific illiteracy and is best addressed through improved science education B) Health misinformation is primarily a supply-side problem, and reducing the production of false health claims through platform moderation and regulation would effectively solve the problem C) Health misinformation exploits stable psychological vulnerabilities and serves real needs that evidence-based medicine sometimes fails to address; effective responses must engage with both the supply-side information environment and the demand-side psychological and social conditions D) Health misinformation is an inevitable consequence of free speech and is best left to market forces to correct

Show Answer **Correct Answer: C** The chapter's analysis supports a multifactorial conclusion. Health misinformation is not simply a problem of illiteracy (educated people are susceptible), nor simply a supply-side problem (misinformation producers respond to demand), nor a problem that free markets reliably self-correct (patent medicine persisted for decades despite causing obvious harm). Effective responses must address: the supply side (platform moderation, regulation of fraudulent health claims); the information environment (inoculation, prebunking, improving access to trustworthy sources); the messenger credibility problem (deploying trusted community figures); the institutional trust deficit (addressing real authority failures that rationally motivate distrust); and the underlying needs that health misinformation serves (hope, autonomy, community, meaning). No single intervention is sufficient.
