Choose the option that changes the given sentence into a simple sentence without changing its meaning:
As soon as Ankita entered the exam hall, she switched off her phone.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → On entering the exam hall, Ankita switched off her phone.
Changing a complex sentence into a simple sentence:
- The given sentence has a time part, “As soon as Ankita entered the exam hall”, and a main part. A simple sentence has only one main verb.
- The time part becomes On entering the exam hall. “On + -ing” means “as soon as”. “Ankita” moves to the main part as its subject.
Why the Other Options are Incorrect?
Option 1: Entering the exam hall, her phone was switched off by Ankita. — Incorrect. The opening “Entering the exam hall” must belong to the subject. Here the subject is “her phone”, so it says that the phone entered the hall.
Option 3: On entering the exam hall, Ankita had switched off her phone. — Incorrect. This changes the time. “Had switched off” says the phone was off before she entered, but the given sentence says she switched it off as soon as she entered.
Option 4: As soon as entering the exam hall, Ankita switched off her phone. — Incorrect. The option says “As soon as entering”. “As soon as” is a joining word, so it needs a full clause with a subject and a verb, not an -ing form alone.
