Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → does she?
Question tags:
- Rule: a negative statement takes a positive tag, and a positive statement takes a negative tag.
- The tag is made of:
- The helping verb of the statement.
- A pronoun for the subject.
- This sentence:
- "She doesn't really know" is negative, so the tag is positive.
- The helping verb is does (simple present with "know").
- The subject is she.
- Complete sentence: She doesn't really know how to get out of the problem, does she?
Why the Other Options are Incorrect?
Option 1: Isn't she? — Incorrect. It uses "is", which is not the helping verb of the statement, and it is negative after a negative statement.
Option 2: doesn't she? — Incorrect. The helping verb is right, but a negative statement needs a positive tag.
Option 4: Is it? — Incorrect. The subject is "she", not "it", and the helping verb is "does", not "is".
