I have some doubt on E. It uses twice the number to compare with the percentage of people reported.
I dont know whats wrong with A?

I vote for (E).

"Those" has no clear referrence.
"Number" is better to refer to "20"%.

Only E is right.

A & B - Instant Kill
C - Kill - Twice "those" - The comparison is focused on the percentage
D - Kill - Should be "many" not "much"

Leaves only E - the correct answer

a) those has no referant
b) to double does not properly introduce a modifier
c) same as A
d) same as A
e) the only option that is unambiguous.

I choose E.
