Question
Directions: In each of the questions, a sentence has
been divided into four parts, one of which may contain an error. Identify that fragment and mark it as your answer. Mark (E) if the sentence contains no error. While several measures have been taken over the years to clean up (A)/ fuels and technology across transport and industry sectors, (B)/ and control dust sources, more action are needed at a scale (C)/ and speed to address the remaining policy gaps for meeting the clean air targets. (D)/ No error (E)Solution
The error is in the verb agreement. "Action" should be "is" (singular) instead of "are" (plural).
