Question #N940

The new policy, which was widely supported by employees, requires that all workers wear safety glasses ______ working with machinery.

Which choice completes the text so that it conforms to the conventions of Standard English?
A. while
B. during
C. whenever
D. as long as

Correct Answer is: B

The correct answer is "during." The preposition "during" is used correctly to show that the workers are required to wear safety glasses while they are performing the action of working with machinery. The other choices are incorrect because they do not convey the correct meaning. "While" is used to show that two actions are happening at the same time. "Whenever" is used to show that an action is done every time something else happens. "As long as" is used to show that an action continues for a certain period of time. None of these choices conveys the correct meaning of the sentence.
