Statement: If it is easy to become an engineer, I don't want to be an engineer. Assumptions: An individual aspires to be professional. One desires to achieve a thing which is hard earned.

Given data

• Statement: 'If it is easy to become an engineer, I don't want to be an engineer.'
• Assumption I: An individual aspires to be professional.
• Assumption II: People prefer achievements that are hard-earned (high difficulty adds value).

Concept/Approach
The speaker's preference is conditioned on difficulty: if easy, the goal loses appeal. This presupposes valuing difficulty itself.

Step-by-step reasoning
I: A vague truism about aspiring to be a professional is not required; the speaker explicitly rejects a profession if it is easy.II: The entire conditional hinges on the belief that only hard-earned achievements are desirable. Hence II is implicit.

Verification/Alternative
Negating II (difficulty doesn't matter) collapses the speaker's reasoning. Negating I does not affect the conditional.

Common pitfalls

• Accepting a generic ambition statement (I) as necessary when the statement actually expresses a conditional aversion.

Final Answer
Only assumption II is implicit.
