If Kwesi _____ listened attentively to his tutor, he would have passed the promotional examination.

Answer and explanation

Correct answer: B. had

  1. Step 1: Third conditional sentences express an unfulfilled past condition using 'had' plus past participle in the conditional clause. Step 2. The main clause 'would have passed' requires the past perfect auxiliary 'had' in the if-clause. Answer: had. Why not the others: 'Has' and 'have' are present forms; 'would have' is redundant and ungrammatical in the conditional clause.
