There is no doubt that one has to keep . . . . . . . with the changing times.

aside
oneself
pace
himself E. tuning

The correct answer is C. pace.

The phrase “keep pace with” means to keep up with the speed or progress of something else. In this case, the speaker is saying that it is important to keep up with the changes that are happening in the world.

The other options are not as relevant to the meaning of the sentence.

  • A. aside: This means to put something to one side or to ignore it. This does not make sense in the context of the sentence.
  • B. oneself: This means one’s own self. This is not the same as keeping up with the changing times.
  • D. himself: This is the reflexive pronoun for “he.” This does not make sense in the context of the sentence.
  • E. tuning: This means to adjust something to make it correct or to make it work properly. This does not make sense in the context of the sentence.
