Question

    Read each sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark "No Error" as your answer. (Ignore the errors of punctuation, if any).

    A large part of his success over the (A) / last year

    owes itself to this more (B) / urgent style of play, which conserves both (C) / energy and discomfits the opponent. (D) / No error. (E)
    A A Correct Answer Incorrect Answer
    B B Correct Answer Incorrect Answer
    C C Correct Answer Incorrect Answer
    D D Correct Answer Incorrect Answer
    E E Correct Answer Incorrect Answer

    Solution

    Replace CONSERVES BOTH with BOTH CONSERVES. Conserving energy and discomfiting the opponent are two different  activitites. Thus, BOTH should be used before these activities. Use of BOTH after CONSERVES would mean that two things are being conserved but this is not the case here. A large part of his success over the last year owes itself to this more urgent style of play, which both conserves energy and discomfits the opponent.
