Out of the public's interest in the details of and conflicts in other people's lives have grown a booming market for "reality" television shows, which are bringing "regular" people onto the television screen with increasing frequency.

A. other people's lives have grown a booming market for "reality" television shows, which are bringing
B. other people's lives has grown a booming market for "reality" television shows, which are bringing
C. another people's lives has grown a booming market for "reality" television shows, which is bringing
D. other people's lives has grown a booming market for "reality" television shows, which is bringing
E. other people's lives has grown a booming market for "reality" television shows, which bring

Guys please reason out your answer to this question!

To understand this question in its logical perspective, one needs to appreciate that the shows themselves create the interest by virtue of their sensational nature and therefore people throng to see them. Therefore, it is clear that the shows entice people. Then a demand emerges and the commercial people step in to cash in on the ready-made boom to make easy money. Therefore, the booming market is the end of the chain and not the beginning.
If this tenet is clear, then this can be easily solved. Here the verb has to be plural either -are bringing or a simple present tense bring. It is now the importance of the increasing frequency can be realized. It a frequently changing one means that it is a dynamic factor and an on- going affair. What better way could be there than to describe in a progressive tense—namely, are bringing. Please also note that choice B meticulously abides by the touch rule of relative pronoun. Therefore, B is the best IMO.
Kaplan’ choice of D as the official answer is understandable, considering Kaplan’s fancy for gaining popularity more through controversies than through logic

The trap of the passage is to convolute it by reverse writing, while the trick of the solution is to write in the normal form.
The original sentence reads as:

Out of the public's interest in the details of and conflicts in other people's lives have grown a booming market for "reality" television shows, which are bringing "regular" people onto the television screen with increasing frequency.

The reversed order will be

A booming market for "reality" television shows have grown out of the public's interest in the details of and conflicts in other people's lives, which are bringing "regular" people onto the television screen with increasing frequency.
After flipping, you may now realize that the subject of the main clause is not public interest but a booming market. All the same, the subject is still is singular and there is no issue about the singular verb has grown. Therefore, A is gone

You mean to say that the use of another has no place in this context, I suppose. Therefore, C is out and I couldn’t agree more

It is not clear what you imply by saying we need future tense verb+ing and so E is out.
I have a doubt that you are rather taking verb+ing as future tense. Verb+ ing (here in this case bringing) is never a future tense. It can be a present participle or a gerund. It can be part of past progressive when we say - was or were bringing-, part of present progressive when we say is/are brining or part of a future progressive when we say will be bringing. When we use them in progressive tenses, we need to combine them with a suitable auxiliary verb to mark the tense.

In the last check, you have just stopped short of the end. It is not the interest that brings the people. The passage makes it clear in the very beginning itself that the interest is in the details and conflicts of other people’s lives. Therefore, it is the shows that draw the crowds. All that I explained in my previous note was just that. I am sorry you could not make much out of it.

However, I wonder how the flouting of the touch rule of, which is excused in Choice D. Choice B truthfully follows this touch rule creed and hence is grammatically superior to D unless somebody wants to go out of the way to justify the modification of which with the distant interest

@ vibhav

Chose B over E for nothing much of grammatical reasons. Since the people are being drawn with increasing frequency, it looks like an on-going thing. So I think a progressive tense such as which are bringing will be better than just a staid present tense which we bring

@daagh thanks. I was pretty confused if i should pick present progressive tense, since most materials say that gmat prefers simple tenses! Any ways I think in the context of this sentence progressive tense seems better. Though it would be of good help if you could pull out some rule that helps to make such a choice in tenses.

My answer was E.

Ron has answered this question very well http://www.beatthegmat.com/reality-tele ... 54890.html
he says B/D could be the answer. This question, though, has a that instead of a which. That means this does not really apply as the modifier has to the closest one. For this one, I guess B would be the best answer.

Missed the fact that continous tense is needed. I make this mistake often.

for the benefit of ppl reading this.. the most important takeaway for me formm that link was
"Use of the simple tense would indicate that the market or television shows always or generally bring(s) people onto the screen with increasing frequency, changing the intended meaning of the sentence.
