Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No Error’ as your answer response. (Ignore errors of punctuation, if any).

During the next (A)/ two weeks, student (B)/ will be asked to defend their(C)/ thesis statements in class(D).

Correct option is B

Correct answer: B

Detailed solution:

Let us examine each part of the sentence carefully.

(A) “During the next”
This phrase is grammatically correct and commonly used. There is no error here.

(B) “two weeks, student”
Here, “student” is a singular noun. However, the sentence later uses “their”, which is a plural pronoun in traditional exam grammar. A singular noun cannot correctly refer to a plural pronoun in this context. Therefore, “student” should be “students.”
This makes part B incorrect.

(C) “will be asked to defend their”
The verb structure is correct. The issue is not with “their” itself, but with its mismatch with the singular noun “student.” Hence, this part is not considered the error location.

(D) “thesis statements in class”
This part is grammatically correct and idiomatic.

Corrected sentence:
During the next two weeks, students will be asked to defend their thesis statements in class.

Final Answer: B
