The pace of life gets faster every day and the world around us becomes more and more fragile.

Which meaning in the dictionary should i choose?
  1. speed of events/changes
  2. walk/run
  3. step
  4. keep pace (with something/somebody)
  5. go through your paces
  6. put somebody/something through their paces
  7. set the pace
  8. force the pace
  9. be able to stand the pace
To all forum expertise. Please advice me how to select the meaning in the dictionary to suit the above sentences.
Welcome to English Forums!
pace is a noun in your sentence, so definitions 4 - 9, which are verbs, should be ignored.
Only the first of the three possible definitions works. pace is basically speed.
