Choose the correct option to complete the following sentence:
They eventually realized that ________.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → they were moving in circles.
Sequence of tenses:
- When the main verb is in the past ("realized"), the verb in the that-clause also goes into a past form.
- An action that was going on at that time takes the past continuous: was/were + -ing.
- This sentence: "they" takes were, so "they were moving in circles".
Complete sentence: They eventually realized that they were moving in circles.
Why the Other Options are Incorrect?
Option 1: they are move on circles. — Incorrect. "are move" is not a verb form, and the idiom is "in circles", not "on circles".
Option 3: they is moved in circles. — Incorrect. "they is" breaks subject-verb agreement, and the passive "is moved" changes the meaning.
Option 4: they will have been move in circles. — Incorrect. "will have been move" is not a correct form (it would need "moving"), and the future does not follow the past "realized".
