Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Rivers has been.
- The error lies in option 2 because of the wrong use of "Subject-verb agreement".
- We need to replace "Has" with "Have" for making the statement grammatically correct.
Grammatical concept:-
- Subjects and verbs must AGREE with one another in number (singular or plural). Thus, if a subject is singular, its verb must also be singular; if a subject is plural, its verb must also be plural.
- The subject of the given statement is plural hence, we need to use a plural verb here.
- The chosen option contains the Grammatical Error hence, it will be the correct choice.
Correct Sentence:-
Rivers have been of primary importance for human settlements since ancient times.
