Question

Choose the option that completes the sentence correctly.

It is not an easy job _____ him.

• A. To convince
• B. To have convinced
• C. Of convincing
• D. Convince

Answer 1

The correct option is A To convince

This sentence has the following form: subject + to be + adjective + to-infinitive + (rest of sentence). This is a common structure for sentences that use the infinitive form of the verb (that is, the 'to + base form of verb). Hence, we need to use the to-infinitive verb form of 'convince' which is 'to convince'.
