Question
The researcher, along with his colleagues, (1)/ have
been invited to present (2)/ their findings at the (3)/ international conference. (4) The following sentence has been split into four segments. Identify the segment that contains a grammatical error and select the option which rectifies that error. If no error is present then mark option 5 i.e., 'no error' as your answer.Solution
The error is in part 2. The subject of the sentence is "The researcher," which is singular. The phrase "along with his colleagues" does not change the singular subject. Therefore, the verb should be "has," not "have." The correct sentence is: "The researcher, along with his colleagues, has been invited to present their findings at the international conference."
