When I get angry, (A)/to count to ten (B)/has always
prevented me (C)/from bursting out (D). Read each sentence to find out whether there is any grammatical 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
Here, ‘to count’ is incorrect. Instead, ‘counting’ should be used. When I get angry, counting to ten has always prevented me from bursting out.
