Select the most appropriate option that can substitute the underlined segment in the given sentence.
The participants are rehearse their roles.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. are rehearsing.
The original sentence "The participants are rehearse their role" is incorrect.
It improperly combines the helping verb "are" with the base form of the verb "rehearse".
The helping verb "are" should be followed by the present particle form of the verb, which in this case is "rehearsing".
Hence, the correct answer would be 'are rehearsing'.
