Statement: “Buy the most contemporary design. You will be seen driving the latest; and if you want to sell later, you will get a good price.” — Car advertisement. Assumptions: I. People prefer models with high resale value. II. A car’s design plays an important role in purchase decisions.

Introduction / Context:
This advertisement appeals to two levers: social image (“seen driving the latest”) and economic value (“good resale”). We test which assumptions support this message.

Given Data / Assumptions:

• Design contemporariness affects perceived status.
• Resale value matters to buyers.

Concept / Approach:
For an ad to be persuasive along specific lines, it must assume its audience values those very lines.

Step-by-Step Solution:
I: The promise of good resale is persuasive only if buyers care about resale value. Implicit.II: Emphasising “most contemporary design” assumes design is an important purchase driver. Implicit.

Verification / Alternative check:
Were either factor unimportant to consumers, the messaging would lose force.

Why Other Options Are Wrong:
“Only I/Only II” omits a necessary assumption; “Neither/Either” mischaracterises the dual emphasis.

Common Pitfalls:
Assuming advertisements only rely on one motivator when they explicitly use two.

Final Answer:
Both I and II are implicit.
