Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:This is a persuasive advertisement. It leverages student/parent desire for success and claims a reason (“excellent teaching by excellent teachers”) for achieving it. Identify the beliefs the ad relies on to be effective. Given Data / Assumptions: I: “Sure success” is a valued goal for the audience. II: Students who join tuition generally look for guaranteed success. III: Excellent teachers alone do not ensure success (a statement that undermines the ad’s claim). Concept / Approach: Persuasion assumes the audience values the promised benefit (I) and that the promise matches audience expectations (II). III contradicts the ad’s implied causal pitch (“excellent teaching” → “sure success”), so it cannot be an assumption of the advertiser. Step-by-Step Solution: Keep I: Without the desirability of “sure success,” the message would not resonate.Keep II: The ad implies that students join tuition seeking assured results; it aligns with audience expectations to be persuasive.Reject III: It runs counter to the ad’s own reasoning; advertisers would not assume a premise that weakens their promise. Verification / Alternative check: If I or II is false, the advertisement loses appeal. If III were true as an assumption, the ad’s claim would be incoherent. Why Other Options Are Wrong: II and III or I and III include a premise that negates the ad. Only II ignores desirability. “All” includes the self-defeating III. Common Pitfalls: Mistaking a possible real-world caveat (“teachers alone may not suffice”) for the advertiser’s assumed premise. Final Answer: Only I and II are implicit
