Critical Reasoning — Implicit Assumptions Remark by a college student: “Everyone desires to buy a personal computer.” Assumptions to test: I. Personal computers are not a need but a luxury. II. Using personal computers improves the quality of skill.

Introduction / Context:
The student makes a broad claim about desire to own PCs. We examine whether this statement requires assuming anything about luxury status or skill improvement.

Given Data / Assumptions:

• Main claim: universal desire to buy a PC.
• Assumption I: PCs are a luxury rather than a need.
• Assumption II: PC use improves skill quality.

Concept / Approach:
A statement about desire does not require claims about necessity/luxury or about outcomes from use. People may desire items for multiple reasons (status, entertainment, study), and the speaker need not assume a specific justification.

Step-by-Step Solution:

Verification / Alternative check:
Negate I and II; the desire claim could still be uttered (rightly or wrongly). Thus neither assumption is required for the statement to be meaningful.

Why Other Options Are Wrong:

• Any option including I or II adds a rationale not demanded by the bare assertion of desire.

Common Pitfalls:
Reading reasons into a preference claim. The statement sketches breadth of desire, not reasons.

Final Answer:
Neither I nor II is implicit
