the general usage is "Require someone TO do Something".

so that leaves us B and D.

in D -- they is ambigious so i would choose B.

Has anyone found an answer to this question... i cannot seem to understand what the ask is based on the information given.

Ron -- would you choose D then

Lemme try this

One meter thirds -- 33.33,66.66,100

One meter fifths -- 20,40,60,80,100

So the total lenghts are -- 20,13.33,6.66,20,6.66,13.33,20

what is the ask on the question??

Jamie -- can you please explain where the approach that I was taking was going wrong.

Thanks

Ron -- Thanks for the insight.. I just could not figure out what the ask was.

Now i understand the question.

In my opinion -- the incorrect portion in choice B is the usage of "Following" when it actually should be either SINCE or POST.
