Question

Combine the following sentence by using an infinitive:
John came early to school. He attended the extra class.

• A. John came early to school so he attended the extra class.
• B. John came early to school but attended the extra class.
• C. John came early to school and attended the extra class.
• D. John came early to school to attend the extra class.

Answer 1

The correct option is D John came early to school to attend the extra class.

The structure of the infinitive is to+ the verb in its basic form, here, "to attend". Hence, Option D is correct. The rest of the options do not adhere to the rule, hence incorrect.
