Critical Reasoning — Assumptions Advertisement: “Use X-brand shoes. These are durable and available in all sizes.” Which assumptions are implicit?

Introduction / Context:
An advertisement highlights durability and size availability to persuade buyers. We must find the assumptions behind this persuasion strategy.

Given Data / Assumptions:

• I: Normally people like durable shoes.
• II: Very few people read advertisements in a newspaper.
• III: Very few people read the newspaper “A.”

Concept / Approach:
Effective ads assume that the features promoted are valued by the audience and that the medium reaches enough potential buyers. Claims that “very few read” the ad or the paper would actually undercut the campaign.

Step-by-Step Solution:
1) I is a natural assumption: promoting durability only makes sense if durability matters to customers. Negating I (“people do not value durability”) weakens the ad’s appeal.2) II and III are contrary to the ad’s purpose. If very few read ads or the specific newspaper, placing the ad there would be inefficient. The advertiser would not assume self-defeating conditions.3) However, among the answer choices provided, there is no option that states “Only I is implicit.” Therefore, the best matching option is “None of these.”

Verification / Alternative check:
Advertising logic relies on highlighting valued attributes (durable, all sizes) to a sufficiently large audience. Minimal readership is not a supportive assumption.

Why Other Options Are Wrong:

• Only I and II / All are implicit / None is implicit / Only I and either II or III: Each includes at least one anti-advertising assumption (II or III) or denies the obvious (I).

Common Pitfalls:
Beware of choosing options that smuggle in negative assumptions about the reach of the medium.

Final Answer:
Only I is implicit; hence, among the listed options, “None of these” is correct.
