Week 3 — Quiz (auto-graded) · Selecting a Topic, Purpose & Thesis

Course: Public Speaking — Fundamentals of Oral Communication (COMM 1) · Silver Oak University (fictional sample) · Prof. Marchetti
Objective tested: Objective 2 — the three general purposes; the specific purpose statement; the thesis (central idea); narrowing a topic; classifying well-formed vs. flawed specific purpose statements.
Points: 10 (1 each) · Assignment group: Quizzes (10% of grade) · Due: end of Module 3.

This is the human-readable quiz with its vetted answer key and feedback. The import-ready Classic QTI is in F-quiz-week-03-qti.xml (generated by the shared validated script — parses with 10 items, every single-answer item exactly one correct). The reusable item-bank entries and the Canvas placement block are at the bottom of this file.

Blueprint

No trick questions; distractors target the Week 3 misconceptions named in the lecture outline (thesis as a question; specific purpose = thesis; two ideas in one specific purpose; not audience-centered).

Questions, key, and feedback

Q1 (MC). Which of the following BEST describes a speech's general purpose?
- A. a single infinitive phrase stating what the speaker wants the audience to learn or do
- B. a one-sentence declaration of the speech's main message
- C. the broad category of the speech's intent — to inform, to persuade, or to entertain/mark an occasion ✅
- D. the narrowed topic chosen from a brainstorming list
Feedback: The general purpose is the broadest label for what a speech aims to do — it is one of three categories. (A is the specific purpose; B is the thesis; D is just the narrowed topic.)

Q2 (MC). A well-formed specific purpose statement is best written as —
- A. a declarative sentence stating the speech's main message
- B. a single infinitive phrase stating what the speaker wants the audience to learn, do, or feel ✅
- C. a question the speech will answer
- D. a list of the speech's three main points
Feedback: The specific purpose always takes the form of a single infinitive phrase (e.g., "To inform my audience about…"). (A is the thesis; C is a research question; D is not a purpose statement at all.)

Q3 (MC). A student writes this specific purpose: "To inform my audience about nutrition and exercise and sleep habits and stress management." What is WRONG with it?
- A. it uses an infinitive phrase, which is incorrect
- B. it contains too many ideas — a well-formed specific purpose covers ONE focused idea ✅
- C. it is audience-centered, which is not required
- D. it is a persuasive purpose, not informative
Feedback: A well-formed specific purpose covers exactly ONE idea. Four ideas crammed into one specific purpose means four different speeches. (A is wrong — an infinitive phrase IS the correct form; C is wrong — audience-centeredness IS required.)

Q4 (MC). What is the KEY difference between a specific purpose statement and a thesis (central idea)?
- A. the specific purpose is a declarative sentence; the thesis is an infinitive phrase
- B. the thesis states the speaker's goal; the specific purpose states the speech's message
- C. the specific purpose is an infinitive phrase stating the speaker's goal (a planning tool, not spoken verbatim); the thesis is a full declarative sentence stating the speech's message (spoken in the speech) ✅
- D. there is no difference — they are interchangeable terms
Feedback: Specific purpose = infinitive phrase, your goal, a planning tool (NOT spoken aloud verbatim). Thesis = full declarative sentence, the speech's message, spoken in the speech. They are never interchangeable. (A and B swap the forms; D is categorically wrong.)

Q5 (Matching). Match each term to its correct description.
| Term | Correct meaning |
|---|---|
| General purpose | The broad intent of a speech: to inform, to persuade, or to entertain/mark an occasion |
| Specific purpose | A single infinitive phrase stating exactly what the speaker wants the audience to learn, do, or feel |
| Thesis (central idea) | A full declarative sentence stating the speech's main message |
| Topic | The subject the speech is about, before purposes are stated |
Feedback: The classic mix-up is specific purpose (an infinitive phrase, your goal, NOT said aloud verbatim) vs. thesis (a declarative sentence, the speech's message, said aloud). The topic is just the subject — the raw material before any purpose or claim is formed.

Q6 (MC). Which of the following is the BEST-formed specific purpose statement?
- A. Affordable meal prep.
- B. Why is meal prep important for college students?
- C. To inform my audience about three strategies for affordable weekly meal prep. ✅
- D. Meal prep is important because it saves time, money, and reduces stress.
Feedback: (C) is a well-formed specific purpose: a single infinitive phrase, audience-centered, one idea, and achievable in a short speech. (A is just a topic fragment; B is a question; D is a declarative sentence — the form for a thesis, not a specific purpose.)

Q7 (True / False). A thesis (central idea) can be written as a question, such as "What are the benefits of strength training?"
- True
- False ✅
Feedback: False. A thesis is always a full declarative sentence that asserts the speech's main message. A question does not assert anything — it only raises an issue. "Strength training improves metabolic health, reduces injury risk, and boosts mood" is a thesis; "What are the benefits of strength training?" is a research question.

Q8 (MC). A student has the broad subject "technology" and is preparing a 5-minute informative speech. Which of the following shows the BEST narrowing for the time limit?
- A. technology
- B. the history of technology
- C. how to set up two-factor authentication on a smartphone ✅
- D. technology, social media, and mental health
Feedback: (C) is narrow and focused enough to cover well in five minutes for a general college audience. (A is too broad; B could fill a semester; D covers multiple large topics that would require much more time.)

Q9 (MC). Which specific purpose statement is MOST audience-centered?
- A. I want to talk about sleep deprivation.
- B. Sleep deprivation is a serious problem.
- C. To persuade my audience to adopt a consistent sleep schedule. ✅
- D. Sleep, fatigue, and performance.
Feedback: (C) is audience-centered: it states what the audience will gain or do, in proper infinitive-phrase form. (A is speaker-focused; B is a declarative sentence — the form for a thesis; D is a topic fragment, not a purpose statement.)

Q10 (Multiple answer — select all that apply). Which of the following are characteristics of a WELL-FORMED specific purpose statement? Select all that apply.
- A. It is phrased as a single infinitive phrase (e.g., "To inform…", "To persuade…") ✅
- B. It covers only ONE idea ✅
- C. It is audience-centered (refers to what the audience will gain) ✅
- D. It is a complete declarative sentence stating the speech's main message
- E. It is achievable within the allotted time ✅
Feedback: A well-formed specific purpose passes four tests: single infinitive phrase (A), one idea (B), audience-centered (C), and achievable in the time limit (E). (D) describes the thesis, not the specific purpose — the thesis is the declarative sentence; the specific purpose is the infinitive phrase.

Answer key (quick reference)

Quality gate (self-checked): each single-answer item (Q1, Q2, Q3, Q4, Q6, Q7, Q8, Q9) has exactly one correct option; the matching item (Q5) pairs four terms to four distinct meanings, one-to-one; the multiple-answer item (Q10) marks exactly four of five choices correct (A, B, C, E — D is the distractor). No item asserts a fact outside the Week 3 course definitions. No quotation or statistic is used, so there is nothing to misattribute. No computation in this course, so there is no arithmetic to mis-key.

Item-bank entries (for variants + the midterm/final)

All ten items are tagged course=COMM1 · week=3 · objective=2 · topic=topic-purpose-thesis and deposited in Item Bank: Week 3 — Selecting a Topic, Purpose & Thesis. The midterm (Week 8) and per-term variant updates draw fresh items from this bank. (Tags: q1 general-purpose, q2 specific-purpose-form, q3 flawed-two-ideas, q4 sp-thesis-distinction, q5 term-match, q6 well-formed-sp, q7 thesis-not-question, q8 narrowing-time-filter, q9 audience-centered-sp, q10 well-formed-sp-characteristics.)
