Question
Only a few dozen sequences (1)/of these variants (2)/has
been reported (3)/from a handful of countries (4). 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
Since ‘these variants’ is plural, ‘has been’ should be changed to ‘have been’. Only a few dozen sequences of these variants have been reported from a handful of countries.
