OA: E
my answer was B
what is the problem with B

I have changed the ans-choice's color so as to let the first time viewer have unbiased attempt.

[poonamchiK]

my answer is b which appears most appropriate.

[sureshnmishra]

in opt B, are having is not parallel with use computers and access the internet, that is why B is not correct.

[d_taneja]

B is wrong because
All over the world, 80 percent of the people use a computer, 60 percent access the internet and 40 percent are having a computer at home.

use and access both are present simple tense while are having progressive -- means that 40 are still in the process of having (purchaing) hence not parallel

[rebchua339680]

If 80% of the world use a computer but only 60% access the internet, then the difference of 20% contributes to the group who uses a computer but do not access the internet.
That means 20% have a computer but do not use it.

"are having" in B is wrong.

C and E, both sound right to me. Would prefer E over C because in the later part uses "a computer at home"

unfortunately we can't give you any help on this question, because the question itself is flawed in a way that you won't see on the GMAT. please understand that using practice questions from dubious sources can actually hurt your performance, and be careful which problem sources you use..
