Quiz — Chapter 2: Audience

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

Section 1 — Multiple Choice

1. What is the single most important question to answer before writing anything?

  • A. What format should the document be?
  • B. Who is the reader, and what do they need to do?
  • C. How long should it be?
  • D. What's the deadline?
Answer B. Audience and purpose drive every other decision — what to include, what to cut, what to define, what to lead with. Format (A), length (C), and deadline (D) are real constraints, but they're downstream of knowing who you're writing for. (§2.1)

2. The K-R-A-C framework stands for:

  • A. Knowledge, Research, Accuracy, Citations
  • B. Knowledge, Role/goal, Action, Context
  • C. Keywords, Readability, Audience, Clarity
  • D. Key points, Recommendations, Analysis, Conclusion
Answer B. Knowledge (what they know), Role/goal (why they read), Action (what they do after), Context (how they read). These four force concrete drafting decisions. (§2.2)

3. Dana includes "we used a random forest" in her note to a fellow data scientist but omits it in her memo to the VP. Why?

  • A. The VP wouldn't believe her analysis.
  • B. The detail is decision-relevant to the peer but decision-irrelevant to the VP, so for the VP it's pure cost.
  • C. She's hiding her methodology from management.
  • D. Random forests are too advanced to mention to executives.
Answer B. Information competes for limited attention. For the peer, the model type changes how they interpret and trust the result. For the VP, it can't change what she does (approve budget or not), so it just burns attention and signals Dana misjudged the reader. Same fact, opposite value. (§2.3, "Why Does This Work?")

4. The "curse of knowledge" refers to:

  • A. Knowing too much and becoming arrogant.
  • B. The inability, once you understand something, to imagine not understanding it — causing you to skip what readers need.
  • C. Forgetting your subject matter over time.
  • D. The burden of having to cite all your sources.
Answer B. It's a cognitive limitation, not an attitude. Once you know the "tune," you can't hear the bare "taps" the way a listener does, so you overestimate how obvious your explanation is. It hits experts hardest. (§2.5)

5. Which document's purpose is primarily to persuade?

  • A. A reference manual entry
  • B. Meeting minutes
  • C. A proposal recommending a new tool
  • D. An installation guide
Answer C. A proposal aims to change a decision, so it leads with the recommendation and marshals evidence. A reference entry (A) informs, minutes (B) record, an install guide (D) instructs. (§2.6)

6. Newton's "tappers and listeners" experiment found that tappers predicted listeners would identify the song about 50% of the time. The actual rate was approximately:

  • A. 45%
  • B. 25%
  • C. 2.5%
  • D. 0%
Answer C. About 2.5%. The huge gap between predicted (~50%) and actual (~2.5%) is the curse of knowledge made measurable: tappers heard the full song internally and couldn't imagine the listener heard only taps. (§2.5)

7. A bridge inspector finds a beam that must be replaced within six months. For the city council (who controls the budget), the opening should lead with:

  • A. The chloride-induced corrosion mechanism and percent section loss.
  • B. The consequence and the decision: the beam must be replaced within six months, at an estimated cost, to keep the bridge safe.
  • C. A full table of inspection measurements.
  • D. The inspection methodology and equipment used.
Answer B. The council's job is to fund the fix, so lead with the decision-relevant facts (deadline, cost, safety) in plain language. A, C, and D are right for the *structural team*, not the council. Note: the deadline and core danger are identical in both versions — only vocabulary and lead change. (§2.4)

8. "Adapting writing for a non-expert" correctly means:

  • A. Removing information until it's simple enough.
  • B. Translating — keeping the full content, changing vocabulary and order to fit the reader.
  • C. Talking down to the reader.
  • D. Making the document shorter.
Answer B. Adapting preserves the content and changes how it's expressed. Removing information (A) or condescending (C) is "dumbing down," a different and worse thing. Length (D) may or may not change. Dana's blog post holds the same finding as her peer note. (§2.8, Mistake 2)

9. Why is the Challenger case used as a communication failure, not just an organizational one?

  • A. The engineers had the wrong data.
  • B. The engineers were right, but presented their case as engineering documentation (inform) when decision-makers needed a persuasive, decision-ready document with one unmissable conclusion.
  • C. Nobody warned anyone.
  • D. The managers couldn't read.
Answer B. The engineers were correct; the warning failed partly because it wasn't adapted to the audience that had to act. The critical temperature/O-ring relationship was scattered across charts rather than stated once, clearly, up front. Being right wasn't enough. (§2.7)

10. Your email to your manager will likely be forwarded to their boss. This is an example of considering the:

  • A. Primary audience
  • B. Secondary audience
  • C. Hostile audience
  • D. Purpose
Answer B. The forwarder's boss is a secondary audience — someone who reads it beyond your direct recipient. Write the primary reader's document, but don't include anything a secondary reader would misread or weaponize. (§2.8, Mistake 3)

11. A grant reviewer with fifty proposals to read is best described as which reading context?

  • A. A friendly reader with unlimited time
  • B. A hostile adversary
  • C. An exhausted skeptic — write for the tired reader who needs the point fast
  • D. An expert who wants full methodology first
Answer C. Not hostile, but time-starved and skeptical. The "Context" variable says: surface the conclusion fast, make it skimmable, don't bury the point. (§2.2, Variable 4)

12. When you genuinely don't know your audience (e.g., a public README), the chapter recommends:

  • A. Write only for experts; novices can catch up.
  • B. Default framing to the least-expert plausible reader, then layer depth so experts can dig in.
  • C. Skip audience analysis entirely.
  • D. Write four separate documents always.
Answer B. Frame and hook for the least-expert plausible reader; layer detail (summary up top, specifics below, appendix/links) so each reader self-selects depth. (§2.8, "it depends" cases)

Section 2 — True/False with Justification

For each: mark true or false and write one sentence justifying it.

T1. "Good writing" is a fixed property of a text that you can judge without knowing the reader.

Answer False. Quality is a relationship between a text and a reader doing a task; the same sentence is excellent for one reader and useless for another (the chapter's threshold concept). (§2.1, threshold block)

T2. Using more jargon always makes technical writing worse.

Answer False. Jargon is *precision* when the audience shares it (Dana's peer note) and a *barrier* when they don't (her VP memo). The skill is matching jargon to the reader, not minimizing it. (§2.3)

T3. The curse of knowledge affects beginners more than experts.

Answer False. It hits experts harder — the more deeply you know something, the less you can reconstruct not knowing it. Someone who learned it last month often explains it more clearly. (§2.5, Check Your Understanding)

T4. A single well-written document can usually serve four very different audiences equally well.

Answer False (mostly). The audiences' needs genuinely conflict; what an expert needs bores an executive. You either *layer* one document (summary + detail + appendix) or write more than one. (§2.8, Mistake 5)

T5. Naming your purpose (inform/persuade/instruct/record) changes how you structure the document.

Answer True. A persuade-document leads with the recommendation; an inform-document leads with the key fact; an instruct-document leads with the goal then step 1. Wrong purpose → wrong structure (the Challenger error). (§2.6)

T6. For short documents like emails, audience analysis matters less because there's so little text.

Answer False. It matters *more* — short documents have no room to recover from a wrong assumption, and a misjudged first line sinks the whole message. (§2.8 FAQ)

Section 3 — Short Answer

S1. In one sentence each, state what an expert, a manager, and the general public most want from the same technical finding.

Model answer The expert wants to verify the method and reuse it; the manager wants the decision-relevant bottom line and a recommended action; the public wants to understand the idea and find it interesting. Rubric: each role tied to a distinct want/action.

S2. Name three tactics for defeating the curse of knowledge and, in a phrase, why each works.

Model answer (1) Name the jargon — externalizes terms that are invisible inside your head so you can audit them; (2) define on first use — rescues novices without slowing experts; (3) test on a real non-expert — exposes friction the curse hides from you. (Also acceptable: the smart-friend test; wait-then-reread.) Rubric: three distinct tactics + a correct one-phrase reason each.

S3. Complete and explain: a document's required action is not "the reader will _" but "the reader will _." Give a bad (vibe) blank and a good (action) blank for the same scenario.

Model answer Bad/vibe: "the reader will know a lot about my project." Good/action: "the reader will approve the retention budget." The action version is testable and tells you what the document must contain and can omit; the vibe version doesn't constrain anything. Rubric: a clear vibe vs. action contrast for one scenario.

Section 4 — Applied Scenario

AS1. You're a data analyst. You found that a marketing campaign drove lots of sign-ups but those users churn at triple the normal rate — the campaign is attracting the wrong customers. Write a 3–4 sentence message to the VP of Marketing (who championed the campaign and controls its budget). Then, in one line, state your purpose (from §2.6) and why you chose it.

Rubric A strong answer: - **Leads with the decision-relevant finding**, not methodology ("the campaign is attracting customers who leave fast" before any churn-rate mechanics). - **Is diplomatically framed** — the VP championed this; the message must be honest without being an attack the VP would resent or that would read badly if forwarded. - **Includes a recommendation or next step**, not just a problem ("I'd suggest we pause and re-target before scaling spend"). - **Names purpose as *persuade*** (you need the VP to *act* — pause or change the campaign — not merely to know the numbers). If you wrote a neutral *inform* version that just reports the churn rate, the VP can nod and do nothing: that's the classic mismatch this chapter warns against. Score: 4 = all four; 3 = leads well + recommends but misjudges tone; 2 = reports the finding but buries the point or omits the action; 1 = methodology-first or no recommendation.
