In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose 'No improvement'. You were so tired after the game that you nodded through on the couch. Correct Answer Nodded off The underlined part of the sentence is grammatically incorrect and has to be improved. The correct form of phrasal verb to be used here is "nodded off" which is in the past tense since the structure of the sentence is also in simple past. "Nod off" means "to fall asleep". None of the other alternatives can make the sentence meaningful. Hence the correct answer is option 2.
