Directions: Read the sentence carefully to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The number of that part is the answer.

(A) She hesitated to contact him (B) as she did not (C) want him to think (D) she wants his help.

The sentence opens in past tense and the same tense is maintained in (B) and (C), but not in (D). It should be ‘she wanted his help’. It is important that there is no mismatch of tense in one sentence. So, the whole sentence should read as: She hesitated (past) to contact him as she did not want (past) him to think (though in the present tense, it is here to complete the action suggested by ‘did not want’) she wanted his help.
