Question

Instructions [97-98]: Read each of the components of the given sentences and mark the component with the grammatical error.

I. He is capable at
II. twisting any fact
III. without any suspicion
IV. at any time

• A. Only I
• B. Only II
• C. Only III
• D. Only IV

Hint:

Check which preposition normally follows the adjective "capable."

Answer 1

The Correct Option is A

A quick way to check this kind of question is to test each component against a fixed idiom you already know is correct. English always pairs "capable" with "of" ("capable of hard work," "capable of winning"), and it never pairs it with "at."

1. Option A: Correct. Component I says "He is capable at," and that preposition is the wrong one; it must be "capable of." This is the single broken piece.
2. Option B: Wrong. Component II, "twisting any fact," needs no correction.
3. Option C: Wrong. Component III, "without any suspicion," is grammatically sound as it stands.
4. Option D: Wrong. Component IV, "at any time," is a common time phrase and is fine.

So the flawed piece is component I, which confirms option A.
