why is option a incorrect ? (if meaning is the issue plz explain)
You got it: (A) has a meaning issue. To see why, consider the following:
The biggest issue Tim needs to work on is his anger management, particularly when it comes to losing to his toddler at Connect Four.
Here, the verb phrase, "to work on" implies that Tim hasn't yet done the work. At some point in the future, he'll address the problem.
We get a similar usage here. "The largest share for any country
to contribute," makes it sound as though the residents will be contributed at some point in the future. But that doesn't make sense in this context, as the census was from 2000.
Also, the phrase, "largest share
for any country" creates the impression that the share is being given
to the country in question, when, in actuality, the country is
contributing residents.
Because (A) has multiple meaning/logic problems, you can get rid of it.
I hope that helps!
