Question
The viewers are not fools, (A)/they pack up on doubt
and (B)/uncertainty on screen and (C)/hit the remote accordingly (D). Read each sentence to find out whether there is any grammatical/contextual error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark ‘No error’ as your answer (Ignore the errors of punctuation, if any).Solution
The phrasal verb ‘pack up’ means ‘to stop doing an activity’. This is incorrect. The correct phrasal verb is ‘pick up’. ‘pick up on something’ means ‘to notice something that other people have not noticed’. The viewers are not fools, they pick up on doubt and uncertainty on screen and hit the remote accordingly.
