Question

Select the correct grammatical sentence from the following:

• A. The teacher asked the students to thoroughly study this book.
• B. The teacher asked the students thoroughly to study this book.
• C. The teacher asked thoroughly the students to study this book.
• D. The teacher asked the students to study thoroughly this book.

Hint:

Place adverbs like “thoroughly” before the main verb in infinitive constructions: “to thoroughly study”.

Answer 1

The Correct Option is A

- Option (A): "The teacher asked the students to thoroughly study this book." This is grammatically correct. The adverb “thoroughly” is correctly placed before the infinitive verb “study”.
- Option (C): "The teacher asked thoroughly the students..."
This is grammatically awkward. The adverb “thoroughly” is incorrectly placed — it’s modifying the wrong part of the sentence and disrupts natural English word order. Other options:
(B) – Unnatural adverb placement.
(D) – Sounds awkward and stilted.
