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

Step 1: Analyze the question We need a word that is the opposite of "unassuming" and that fits the gap after "whereas", which signals contrast.

Step 2: Explain the concept "Unassuming" means modest, humble, not attempting to draw attention to oneself or show off. Its antonym should describe someone who is proud, self-important, or likes to show off.

Step 3: Check each option

• A. cheerful: means happy. This is not the opposite of modest.
• B. boastful: means bragging and showing off about oneself. This is the direct opposite of modest and unassuming.
• C. loud: means noisy. This is a possible personality trait, but it describes volume rather than attitude. A humble person can be loud, so it is not a true antonym.
• D. rude: means impolite. This is not the opposite of unassuming, since a modest person can still be rude.

Step 4: Answer The sentence reads: "Mrs. Agide is unassuming whereas her twin sister is boastful." This gives a clear contrast between modesty and bragging, so the answer is B.

Exam tip: For antonym questions, define the underlined word first, then pick the option that reverses its core meaning, not one that is merely a different personality trait. Also remember that "unassuming" is related to "assume" in the sense of taking on airs. Someone who does not put on airs is unassuming, and someone who does is boastful.
