Critical reasoning — identify implicit assumptions Statement (advertisement by an airline): “Fly with us and experience the pleasure of flying.” Assumptions to evaluate: I. More passengers may be attracted to travel with the airline after reading the advertisement. II. People generally prefer an enjoyable, comfortable flight experience. III. Other airlines may not be offering the same facilities.

Introduction / Context:
Airline ads promise an enjoyable experience to persuade potential travelers. We must determine which assumptions are necessary. Typically, an ad presumes its ability to attract customers and taps into a universal preference for comfort, without needing to claim rivals lack such features.

Given Data / Assumptions:

• An airline invites travelers to “experience the pleasure of flying.”
• I: The ad will influence at least some readers to choose the airline.
• II: Passengers value enjoyable, comfortable flights.
• III: Competitors do not offer similar facilities.

Concept / Approach:
An implicit assumption must be indispensable to the persuasion attempt. Influence (I) and preference for comfort (II) are central. However, exclusivity against competitors (III) is not necessary; a brand can still advertise shared benefits and compete on perception or degree.

Step-by-Step Solution:

Verification / Alternative check:
Brands routinely advertise benefits that are not strictly unique but are still persuasive when framed compellingly, confirming that I and II suffice.

Why Other Options Are Wrong:

• Only I / Only II / Only III: Miss at least one necessary element or assert an unnecessary one.
• None is implicit: Ignores the basic persuasion and preference assumptions.

Common Pitfalls:
Believing an ad must assume uniqueness; many campaigns compete on parity features but better promise or service.

Final Answer:
Only I and II are implicit
