Question

Read each of the components of the given sentence and identify the component with the grammatical error:

P. The government
Q. has been working
R. on this project
S. from the last 20 years

• A. P
• B. Q
• C. R
• D. S

Answer 1

The correct option is D S

Here, the use of 'from' in part S of the sentence is incorrect. Both 'since' and 'from' are used to express duration and both tell us the starting point of an activity but only 'since' is used to express the duration of an unfinished action, up to a point in the present. So, in the given sentence 'since' should replace 'from' for a correct sentence construction. Option D is the answer.
