However, a large number of employees kept . . . . . . . from their offices today.

on
out
away
up

The correct answer is: C. away

The word “away” means “at a distance from a particular place.” In this sentence, it is used to describe the fact that a large number of employees were not at their offices today.

The other options are:

  • A. on – This word means “in a state of being active or functioning.” It does not make sense in this sentence, because it does not describe the fact that the employees were not at their offices.
  • B. out – This word means “not in or at a particular place.” It could be used in this sentence, but it would be less specific than the word “away.”
  • D. up – This word means “to a higher position or level.” It does not make sense in this sentence, because it does not describe the fact that the employees were not at their offices.

I hope this helps!
