Question

    The following sentence has been divided into four segments.

    Identify the segment that contains an error. The teacher asked the students / that whether they / had completed / their homework.
    A their homework Correct Answer Incorrect Answer
    B had completed Correct Answer Incorrect Answer
    C that whether they Correct Answer Incorrect Answer
    D The teacher asked the students Correct Answer Incorrect Answer

    Solution

    The expression "that whether" is incorrect because both words are used to introduce indirect questions, but only one should be used.
    The correct construction is: “The teacher asked the students whether they had completed their homework.”
    So, segment 3 is grammatically incorrect.
