Critical reasoning — assumptions (implicit): Statement (advertisement): "Avon Cycles — fast, easy to ride, impressive, reliable, crafted and up-to-date automation." Assumptions: I. There is no other cycle with any of these features. II. People do not bother about the cost.

Introduction / Context:
Advertisements typically highlight product features to persuade buyers. The claim lists speed, ease, reliability, craftsmanship, and modern automation for Avon Cycles. We must decide which assumptions must hold for the ad to function as intended.

Given Data / Assumptions:

• Ad lists desirable features of the product.
• Assumption I: Uniqueness — no other cycle has any of these features.
• Assumption II: Consumers ignore cost.

Concept / Approach:
For an ad to make sense, it need not assume uniqueness; comparative or absolute claims about features can persuade even if rivals share some attributes. Nor must it assume people ignore price; the ad simply emphasizes features, leaving price sensitivity unaddressed. Therefore, neither I nor II is required.

Step-by-Step Solution:

Verification / Alternative check:
Negate I: Other cycles also offer these features — the ad still functions by informing that Avon has them too. Negate II: People do care about cost — the ad still offers reasons (features) that may justify their purchase decision within budget constraints.

Why Other Options Are Wrong:

• Only I/Only II/Either/Both: Each attaches unnecessary assumptions that are not required by the mere act of feature-promotion.

Common Pitfalls:
Assuming ads always claim uniqueness or price irrelevance. Many ads simply highlight benefits without committing to exclusivity or dismissing cost.

Final Answer:
Neither I nor II is implicit
