Question
The scientists called back (A)/more research (B)/to
identify (C)/the chemicals responsible (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 ‘call back’ means ‘to return to a place in order to see someone or collect something’. This is inappropriate here. The correct phrasal verb is ‘call for’, which means ‘to need or deserve a particular action, remark, or quality’. The scientists called for more research to identify the chemicals responsible.
