Question

Fill in the blank with the most appropriate word.
His teacher told him ____ hard.

• A. study
• B. studied
• C. to study
• D. studying

Answer 1

Answer: (C)

to study

Let’s examine the sentence: “His teacher told him ____ hard.” Option C is the correct answer because the sentence seeks to state the activity of ‘studying’ rather than the action of ‘studying.’ The infinitive 'to study’ expresses the notion of studying as an activity rather than the action. Other Options cannot be used as they would render the sentence grammatically incorrect.
