Introduction / Context:
The statement is advisory: it urges consultation before deciding about investments. Advisory statements usually rest on (a) a risk of error without the advice and (b) the value of achieving a correct outcome. We examine whether these two assumptions are necessary for the advice to be meaningful.
Given Data / Assumptions:
- Advice: “Consult us first.”
- Assumption I: Absence of consultation increases the risk of a wrong decision.
- Assumption II: Making the right decision matters (has significant consequences).
Concept / Approach:
- Advice presupposes both a potential downside (error) and a goal (correctness).
- If either is denied, the advice loses force or relevance.
Step-by-Step Solution:
Assess I: If you cannot make a wrong decision without consulting, then consultation is unnecessary. Thus I is implicit.Assess II: If right vs. wrong decisions are unimportant, urging extra care is meaningless. Thus II is also implicit.
Verification / Alternative check:
Remove I or II: In either case, the advisory loses rational motivation, confirming that both are required premises.
Why Other Options Are Wrong:
Only I or only II — each alone does not fully justify the necessity of consultation.Either I or II — incorrect; both are needed.Neither — contradicted by the nature of the advice.
Common Pitfalls:
Forgetting that advice implies both risk and value; otherwise, there is no reason to follow it.
Final Answer:
Both I and II are implicit
