+1 for E.
Difference between X, and Y. So A & B are out.
C is out for incorrect usage of Which
D is awkward and comparing government agents and a searching method

Hi Stiv

"that" and "which" cannot refer to living beings. "who" can.
Here "that" cannot follow "government agents"

Now let us look at option D

There is a big difference between government agents that scan items for explosives or that look through a suitcase full of clothing, and that search through the hard drive of a laptop computer containing work papers

How many types of agents are we considering ("that" is a marker here)
1) scan items for explosives
2) look through a suitcase full of clothing
3) search through the hard drive of a laptop computer containing work papers

The use of between in the correct part suggests that there are only two types. How can we have three?

Makes sense?

1. Please look at this note below s in the given link. http://www.thefreedictionary.com/who

The relevant portion says this much about the use of ‘that and who’

Some grammarians have argued that only who and not that should be used to introduce a restrictive relative clause that identifies a person. This restriction has no basis either in logic or in the usage of the best writers; it is entirely acceptable to write either the woman that wanted to talk to you or the woman who wanted to talk to you. •

But it is not clear whether GMAT accepts this concept. If GMAT has no issue about using that for human being also, then we can refer to the agents as agents that, and not necessarily agents who.

But looking at the meaning part, the first type of search is a more serious one because it is mostly done as security check against international terrorism, while the search through the drives of a computer is less serious one that searches for less harmful cyber crimes. That is where the big difference lies and not in differentiating between two types of people, who both after all are government agents, .Therefore, I feel there should be no need for hair- splitting between the birds of the same feather. This text definitely tests the difference between two searches. D is not that fit as E

I chose quickly and carelessly choice C, but choice E is better. In choice C, there are two error spots: Government agents scanning of items for explosives or looking through a suitcase full of clothing, and searching through the hard drive of a laptop computer which contains work papers
