Critical Reasoning — Assumptions Advertisement (Coaching Institute): “If you are intelligent, we are the right people for improving your performance.” Which assumptions are implicit?

Introduction / Context:
This persuasive message targets “intelligent” students and promises performance improvement. We must determine the required background beliefs.

Given Data / Assumptions:

• I: Brilliant students prefer to join coaching classes.
• II: Coaching classes help the students to improve their performance.
• III: No other institute provides such coaching.

Concept / Approach:
Ads typically assume the offered service is effective (II). They need not assume exclusive capability (III) or an existing preference (I) among the audience; the ad itself aims to create or reinforce that preference.

Step-by-Step Solution:
1) II is necessary: promising improvement presumes coaching can actually improve performance.2) I is not required. The institute is trying to attract intelligent students; it need not assume they already prefer coaching.3) III is unnecessary and extreme. The ad does not claim exclusivity; others may also coach well.4) The correct single implicit assumption is II, but no option lists “Only II.” Therefore, the best match is “None of these.”

Verification / Alternative check:
Negating II (“coaching does not help”) collapses the promise, confirming necessity. Negating I or III leaves the ad’s logic intact.

Why Other Options Are Wrong:

• I and II / II and III / I and III / All: Each includes at least one nonessential or extreme element.

Common Pitfalls:
Do not mistake targeted messaging for proof of an a priori preference or exclusivity.

Final Answer:
Only II is implicit; hence “None of these.”
