Critical reasoning — identify implicit assumptions Statement: “The successful man has the ability to judge himself correctly.” Assumptions to evaluate: I. Inability to judge oneself correctly causes failure. II. Judging others is of no use to a successful person. III. A successful person cannot make a wrong judgement.

Introduction / Context:
The statement attributes one ability to successful people: accurate self-judgement. Our task is to see whether broader claims about failure, judging others, or infallibility are necessary assumptions, or merely tempting extrapolations.

Given Data / Assumptions:

• Claim: Successful people can judge themselves correctly.
• I: Failure results from inability to judge oneself.
• II: Judging others is useless for success.
• III: Successful people never make wrong judgements.

Concept / Approach:
From “X has ability A,” do not infer negations or universals about other abilities or absolute error-free performance. The scope is descriptive, not exhaustive or exclusive.

Step-by-Step Solution:

Verification / Alternative check:
Rephrase: “One trait of many successful people is sound self-assessment.” This stands without I–III.

Why Other Options Are Wrong:

• Any combination or “All” imports claims the original statement never needed to make.

Common Pitfalls:
Equating a cited trait with an exhaustive definition of success; turning a capacity into a claim of infallibility.

Final Answer:
None is implicit
