Question
At least one-third (A)/of all women (B)/over ninety has
(C)/sustained a hip fracture (D). Read each sentence to find out whether there is any grammatical 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).Solution
With words that indicate portions—percent, fraction, part, majority, some, all,none, remainder, and so forth —look at the noun in the‘of’ phrase (object of thepreposition) to determine whether to use a singular or plural verb. If the object ofthe preposition is singular, use a singular verb. If the object of the preposition isplural, use a plural verb. Here, ‘have’ is correct. At least one-third of all women over ninety have sustained a hip fracture.
