(E) twice the number reported in the 1977 survey

In all others, "those" usage is incorrect as it refers to doubling a number or percentage (singular)

^ E ^

the number of the people is doubled so we should have "the number" in the correct answer. In A, C and D "those" is used. It sounds like doubling the people and it is not correct!

B says "to double.." there is not an aim here.

So E is best IMO.

so when the sentence refers to a number like 20 percent, is it always correct to say "double" rather than the idiom "twice as much as"?

I think you cannot form a rule like that.
Here D is wrong because the option cantains "those" which is wrong.

here I think "much" shouldnt be used 'cos we are trying to compare the %of people...E should be it

How can it be E? The sentence mentions percentage, and E references the number of?
