Question

My colleague made his mark as a lawyer at an early age.

• A. secured good marks
• B. distinguished himself
• C. created a vacancy
• D. No correction required

Hint:

Idioms: "make one's mark" = achieve distinction or recognition.

Answer 1

The Correct Option is B

The idiom "made his mark" means "distinguished himself" or "became successful/recognized." Among the options, (b) is the exact equivalent. \[ \boxed{\text{distinguished himself}} \]

Answer 2

Treat "made his mark" as a fixed idiom and test each option by substitution, checking whether the resulting sentence keeps the idiomatic meaning of achieving recognition, not a literal reading.

1. Option A: "secured good marks as a lawyer" wrongly takes "marks" literally, as in examination scores, which has nothing to do with professional recognition.
2. Option B: "distinguished himself as a lawyer at an early age" preserves the idiomatic sense of gaining recognition and standing out in one's profession.
3. Option C: "created a vacancy as a lawyer" has no connection to the idiom's meaning of personal achievement.
4. Option D: the phrase itself is not grammatically wrong, but the option list asks for the closest equivalent meaning, and idiomatic meaning is best tested by substitution rather than leaving the idiom unexplained.

Only option B preserves the intended idiomatic meaning of the original sentence.

Hence, the correct answer is distinguished himself.
