It should be E


- Use of word practical to modify adjective unlimited is wrong which rules out 1, 3 and 4.
- 5 represents the comparison with the use of 'denser' which conveys the intended meaning better than 'dense' does in 2.

2) practically unlimited number of air routes, but they are dense over

5) practically unlimited number of air routes, but they are denser above

in option E, there are 2 flaws
1.) one is use of comparative "denser" and it should be followed by than
2.) Use of "above" changes intended meaning of the sentence

Will say 3 things.

1. Obvious one. Options A, C, D are out because of "practical". There is no sense at all.

2. I do not like conjuction "but" here. If, for example, option C sounded in such manner:
"practically unlimited number of air routes, which are denser over",
I would choose it.

3. Why for me E is better than B.
"but they are denser above" - in this case it feels like we have a set of routes and we then mark out some subset of routes, that are denser
(Similarly it feels about "which are denser over" - even better).
But in case of "but they are dense over" it feels somehow wrong - there is no marking out of routes that are denser than.

Of course it is not strict. Would like to hear explanations from more competent users.

The main difference between B and E is the comparative form denser and I think that denser should be followed by than.Above and over are pretty much same so I think B is a better choice but still looking for an expert reply.

How can we say that the comparison is in play here without the comparison marker, denser ... than?

Mod. rule - adj adj noun ---> correct

Practical unlimited number of air routes = number of air routes that is practical and unlimited.

Adv adj noun ----> meaning practically mod. unlimited

For me this make no sense 2) and 5) are out.

What "they" refers to? Air routes

So I think 3) is the best option

In GMAT it is not expected that a comparative adjective (e.g. "denser") would be used without "than". Thus option E would normally be wrong in GMAT. In that respect, option B is better than option E.

Moreover the singular verb "is" is wrong in all the options. "A number of X" is plural (X is the subject), whereas "the number of X" is singular ("number" is the subject).

Once the part "practically unlimited" is removed, the above would be clear:

A number of air-routes is there.... wrong.
There is a number of air-routes.... wrong.
A number of air-routes are there.... correct.
There are a number of air-routes.... correct.

The phrase "a number of" is similar in meaning to the word to "some".

I believe B changes the meaning by using the word dense. While the original sentence uses a comparison word denser, option B uses dense.
Changing the comparison word denser to dense brings in a subtle change in meaning.

Do correct me if I'm wrong :-)
