In the sentence below, there is one underlined word and one gap. From the list of words lettered A to D…

Analyze the question

The underlined word is "strict" (the sentence reads: "The principal is very strict but his vice is ....."). We need a word that:

1. is most nearly opposite in meaning to "strict", and
2. fits the gap grammatically and logically.

Explain the concept

Strict means demanding obedience, firm, and not allowing rules to be broken. Its antonym is a word meaning relaxed about rules, or tolerant of misbehaviour. The "but" in the sentence signals contrast, so the gap needs a word that contrasts with "strict".

Step-by-step solution

• A. peaceful means calm and free from disturbance. It describes a mood or environment, not how someone enforces rules, so it is not the opposite of strict.
• B. lenient means merciful, tolerant, and not harsh in enforcing rules. This is the direct opposite of strict.
• C. kind means friendly and caring. A strict person can also be kind, so it is not a true opposite.
• D. efficient means working well and productively. It has no connection to strictness.

Answer: B, lenient. It is the true antonym of "strict" and it completes the sentence naturally: "The principal is very strict but his vice is lenient."

Tip: In antonym questions with "but", look for the word that reverses the specific quality described, not just a generally "nice" word. "Kind" is a tempting distractor, but the exact opposite of strict is lenient (or lax). Also remember that "vice" here means "vice-principal", not the moral meaning of the word.
