Quiz — Chapter 14: Research Papers

Target: 70%+ before moving on. Answers and explanations are hidden — try each question before expanding.

Section 1 — Multiple Choice

Q1. The central distinction of this chapter is that a research paper is fundamentally: A. A complete and faithful description of everything you did B. An argument that makes a claim and defends it with the necessary evidence C. A chronological narrative of your research process D. A summary of the existing literature on a topic

Answer **B.** A paper is an *argument*, not a description (§14.2): it makes a specific claim, defends it with exactly the evidence the claim requires, and excludes what doesn't serve it. A and C describe the description-mode failure (everything you did, in the order you did it). D confuses the paper with its literature review, which itself should argue a gap, not just summarize. The test for inclusion is "does this advance the argument?" not "is it true and did I do it?"

Q2. In the hourglass structure, the narrowest (most specific) part of the paper is: A. The introduction B. The methods and results C. The discussion D. The abstract

Answer **B.** Methods and Results are the waist of the hourglass — maximally specific: exactly what you did (replicably) and exactly what you found, with no broad context or implications (§14.4). The introduction (top funnel) starts broad and narrows; the discussion (bottom funnel) starts narrow and widens. The abstract is a compressed version of the whole hourglass, not the narrow point.

Q3. Which is the most damaging flaw in an abstract? A. It's slightly longer than the venue's word limit B. It states that "results are promising" but never says what the result was C. It uses one piece of jargon D. It doesn't cite any sources

Answer **B.** The fatal abstract flaw is describing that results *exist* without stating what they *were* — the abstract's most-hunted sentence is the key result, and "promising" is not a result (§14.5). Give the actual finding, with a number. A is a real but minor fix; C is normal in a specialist abstract; D is expected (abstracts rarely carry citations). No result = no function.

Q4. A "major revision" decision means: A. Your paper has been rejected B. Your paper is accepted as-is C. The reviewers will likely publish it if you address their substantial concerns D. You must submit to a different journal

Answer **C.** Major revision is *not* rejection (§14.6) — it signals the work is worth publishing *if* you address the concerns, which is a vote of confidence wearing a stern face. If reviewers thought the work hopeless, they'd reject outright (A). It is more demanding than "accept as-is" (B). And it's an invitation to revise *and resubmit to the same venue*, not to go elsewhere (D). Treat it as the opportunity it is.

Q5. What makes a hypothesis usable (scientifically meaningful)? A. It predicts a positive outcome for your method B. It is falsifiable — a possible result could prove it wrong C. It is stated as a question D. It avoids committing to any specific number

Answer **B.** A hypothesis must be *falsifiable* (§14.3): there must be a result that would refute it. "Our method will perform well" can't be falsified (no metric, no comparison) and so isn't a hypothesis; "it reduces p99 latency vs. LRU with no throughput penalty" can be contradicted by data. A describes wishful prediction, not falsifiability. C confuses a hypothesis with a research question. D is backwards — specificity (including numbers) is what *makes* it falsifiable.

Q6. A reviewer raises a concern you genuinely disagree with. The best response: A. Ignore it — you can't address every comment B. Reply "the reviewer has misunderstood the paper" C. State your disagreement with evidence and reasoning, respectfully, and offer an alternative D. Concede it even though you think it's wrong, to avoid conflict

Answer **C.** Disagree with *evidence, not attitude* (§14.7): acknowledge the comment, give the specific reasoning or data for your position, and ideally offer what the reviewer actually needs by another route. A is the worst move — an ignored comment reads as evasive to the person deciding your fate. B is accusatory and slams the door; "we may not have made this clear" fixes the real problem (your paper wasn't clear). D abandons defensible science and can introduce errors; conceding should be reserved for points that are actually right.

Q7. In double-blind peer review, you must: A. Keep your identity secret from the editor B. Anonymize your manuscript — remove your name and mask self-citations C. Refuse to cite your own prior work D. Reveal the reviewers' identities

Answer **B.** Double-blind means neither author nor reviewer knows the other's identity, so you must anonymize the manuscript: strip identifying details and mask self-citations ("prior work [12]," not "our prior work [12]") (§14.1). The editor still knows who you are (A is wrong). You may still *cite* your prior work — you just don't reveal it's yours (C is wrong). You don't learn the reviewers' identities; that's the point (D is wrong).

Q8. Which is the clearest sign of a predatory journal? A. It charges an article-processing fee B. It is open access C. It sends unsolicited flattering invitations and guarantees publication within two weeks D. Its peer review takes three months

Answer **C.** Unsolicited flattery plus guaranteed, absurdly fast acceptance is the predatory signature — a guarantee of publication means there is no real peer review (§14.8). A is *not* a reliable tell on its own: legitimate open-access journals also charge fees (the tell is the fee *combined with* no real review). B is normal and often good. D describes *legitimate* review, which is slow — a three-month review is a sign of a real process, not a predatory one.

Q9. The "gap" in a research paper is: A. The space left for figures B. The specific thing the field doesn't yet know that your work supplies C. The difference between your hypothesis and your result D. The missing section a reviewer asks you to add

Answer **B.** The gap is the precise opening in current knowledge that your contribution fills — it's what makes the contribution *necessary*, and establishing it is the job of your literature review (§14.3). "More research is needed" names no gap. A and D are unrelated literal meanings; C confuses the gap (in knowledge) with the relationship between prediction and outcome.

Q10. Why should you choose your target venue before writing the paper? A. To reserve a publication slot B. Because the venue's length limits, format, audience, and conventions shape the paper itself C. Because you can't change venues later D. To find out the impact factor

Answer **B.** Each venue has specific length limits, required structure, citation style, and — most importantly — a *specific audience* that determines how much background you need and how you frame the significance (§14.1). Writing first and choosing later produces a paper framed for no one that must be rebuilt for each submission (and risks a desk reject for being out of scope). A is not how submission works; C is false (you can and often do resubmit elsewhere); D is a minor consideration, not the reason.

Section 2 — True/False with Justification

State true or false and justify in one sentence.

Q11. A paper should include every experiment you ran, because leaving any out is dishonest.

Answer **False.** A paper is an argument, so you *select* the evidence that serves the claim and exclude what doesn't (a failed-because-off-topic experiment) — this is legitimate, and distinct from *hiding contradictory evidence*, which would be misconduct (§14.2; the line is drawn in [Chapter 38](../../part-08-synthesis/chapter-38-ethics-responsibility/index.md)).

Q12. "Major revision" is essentially a polite rejection.

Answer **False.** Major revision means the reviewers will likely publish the paper *if* you address their concerns — it's a conditional path to acceptance and a vote of confidence, not a rejection; reading it as rejection causes people to abandon salvageable papers (§14.6).

Q13. The abstract should be written first, before the rest of the paper, and never touched again.

Answer **False** (both halves are off): writing a *draft* abstract early is useful because it forces you to know your argument, but you must *revise it last*, once you know exactly what you found — it's the most-read paragraph and deserves the most care, not a one-time first draft (§14.5).

Q14. In technical writing, the discussion section is where you state your specific result and then widen out to what it means.

Answer **True.** The discussion is the bottom funnel of the hourglass: it starts narrow (your specific result), then widens to interpretation, relation to prior work, limitations, and implications (§14.4) — the widening is what answers the "so what?" and prevents the "significance unclear" complaint.

Q15. A publication fee always means a journal is predatory.

Answer **False.** Legitimate open-access journals charge article-processing fees too; the predatory tell is the fee *combined with* no real peer review (guaranteed/fast acceptance, fake metrics, unsolicited flattery) — the fee alone doesn't decide it (§14.8).

Section 3 — Short Answer

Two to four sentences each. Model answers and rubrics below.

Q16. Explain the difference between writing a paper as a description and writing it as an argument, and give the test you apply to decide whether a piece of content belongs.

Model answer + rubric A *description* is organized around your activity and includes everything you did, in the order you did it, because you did it — its logic is "here is the evidence of my labor." An *argument* is organized around a claim and includes only the evidence needed to establish that claim, in the most convincing order, excluding the rest. The test for any content is **not** "is it true and did I do it?" but **"does this advance the central argument?"** — and you cut things that are true and cost you weeks if they don't. **Rubric:** names the activity-vs-claim organizing principle (1) and states the "does it advance the argument?" test (1).

Q17. Name the four moves of a strong abstract and identify which one, if missing, is fatal.

Model answer + rubric The four moves are (1) the **gap** (the problem and what's missing), (2) the **approach** (what you did), (3) the **key result, with a number** (your central finding, quantified), and (4) the **significance** (what it means / why it matters). The **result** is the fatal one to omit: an abstract that says results exist ("results are promising") without stating what they were gives the reader nothing to carry away, and it's the most common abstract failure. **Rubric:** all four moves named (1); identifies the missing *result* as fatal and explains why (1).

Q18. A reviewer asks for an experiment you genuinely cannot run. Describe how to handle this comment without being defensive or evasive.

Model answer + rubric Address it explicitly (never ignore it), acknowledge that the request is reasonable, explain honestly why you can't do it (the real constraint), and offer the best available alternative — a partial analysis, a citation that covers the gap, or an explicit limitation added to the discussion. Crucially, adjust any claim the missing evidence can't support, so the paper now claims only what it shows. Editors and reviewers are reasonable about genuine constraints when you're transparent; they turn hostile at evasion or a silent omission. **Rubric:** says to address-not-ignore and explain the constraint honestly (1); says to offer an alternative and/or adjust claims + add a limitation (1).

Section 4 — Applied Scenario

Q19. Below is a weak abstract. (a) Identify which of the four moves are missing or broken. (b) Rewrite it as a four-move abstract; you may invent a plausible result with a number.

WEAK ABSTRACT:
"Air pollution is a significant problem in cities worldwide. This study
looks at the use of green walls to improve urban air quality. We performed
measurements at several sites. The findings are interesting and could be
useful for urban planning."
Answer + rubric (a) The **gap** is generic (names "a significant problem" but not what's actually unknown — e.g., whether green walls measurably reduce specific pollutants at street level); the **approach** is vague ("measurements at several sites" — what was measured?); the **result is entirely absent** ("findings are interesting" is not a finding); the **significance** is empty ("could be useful") because there's no result to ground it. (b) A strong rewrite, e.g.: *"Street-level air pollution harms urban health, and while green walls are widely promoted to mitigate it, field evidence of their effect on specific pollutants is limited. [GAP] We measured NO₂ and particulate (PM2.5) concentrations at 1.5 m height directly beside green walls and matched bare-wall control sites across six locations. [APPROACH] Green-wall sites showed 21% lower mean PM2.5 and 13% lower NO₂ than controls over the eight-week period. [RESULT] These results provide field evidence that green walls can produce measurable street-level air-quality benefits, supporting their inclusion in urban-planning guidance. [SIGNIFICANCE]"* **Rubric:** correctly identifies the absent *result* as the key flaw (1); rewrite includes all four moves *with an actual number* (1).

Q20. You are an author. Below is a reviewer comment with a valid part and an overreach. Write a short response (3–5 sentences) that concedes the valid part and handles the overreach gracefully.

REVIEWER COMMENT:
"The sample size (n=20) is small, which limits the statistical power of the
conclusions. Moreover, the entire approach is flawed because the authors
did not use a randomized design, making the results essentially worthless."
Answer + rubric A strong response concedes the sample-size point honestly and adjusts claims, while pushing back on "worthless" with reasoning, not attitude. For example: *"We thank the reviewer for these points. We agree that n=20 limits statistical power, and we have (1) added this explicitly as a limitation (Discussion, para. 5) and (2) softened our conclusions to describe the findings as preliminary evidence warranting a larger study. On the design: our study used a [matched / within-subjects / quasi-experimental] design rather than randomization because [specific reason — e.g., randomization was infeasible in this clinical setting]; we have clarified this rationale in the Methods (Section 2.1) and added a paragraph discussing how the non-randomized design constrains causal inference. We hope this addresses the concern; we respectfully note that a non-randomized design limits, but does not invalidate, the findings, which we now frame accordingly."* **Rubric:** concedes the sample-size limitation with a specific change (1); pushes back on "worthless" with reasoning and a claim-adjustment rather than defensiveness (1).

Scoring & Next Steps

Score What it means Do this
< 50% Core concepts not yet solid Re-read §14.2 (argument vs. description) and §14.4–§14.5 (hourglass, abstract). Redo Exercises Part A.
50–70% Concepts forming, application shaky Redo Exercises B2 (abstract rewrite) and C3 (reviewer response) — the two ★core tasks. Re-read §14.7.
70–85% Solid — proceed Move to Chapter 15. Do the Project Checkpoint if you skipped it.
> 85% Strong command Try Exercises Part E (reverse-engineer a great paper, write a full mock response letter).

The two skills that matter most here aren't memorized facts — they're whether you can rewrite a resultless abstract into a four-move one with a real number, and respond to a stinging reviewer without a trace of defensiveness. If you nailed Q3, Q6, Q16, Q17, Q19, and Q20, you have the parts that get papers published. Onward to Chapter 15: Literature Reviews, where you'll build the synthesis that establishes the gap your whole paper drives toward.
