I did this question too at 3 AM and damn it: it was really tough and ackward. I' d expect these sort of question during the exam. nasty

At the end of the day: if the number of radio increased and the receiving programs more or less are the same, then the same programs do not reach the entire number of radios.

This is the gist of the argument. People are stressed out on words such as : few if any (clearly means 1 or zero, in a nutshell) losing focus on what really the argument is.


Gmat is really crazy

(Reference is made to explanation given by Karishma ). Further analysis of option 'A' & 'D'.

'A' can be proved wrong

Total no of RDS radio sets in Verdland= 100.Two counties X & Y in Verdland, where the no of RDS radio sets(no of people owing it) are 20 & 80 respectively. Only County 'X' people receive the RDS Broadcast. If people at 'Y' did not receive the RDS Broadcast earlier but now start receiving the Broadcast signal due to what option 'A' states, the increase in no(by 80) of people receiving RDS program is significant in contradiction to the conclusion.
We simply dont know how many RDS radio sets are available (out of the total in the town) at a place where there was no RDS Broadcast earlier.

Whereas option 'D' cannot be proved wrong. It has to be true even if it sounds too simplistic (Even after discounting any other modifications/ways of receiving RDS Broadcast)

The bottom line is :- No of people receiving the broadcast and not the No of programs received by people. The increase in the No of RDS Radio station broadcasting has no bearing on the no of people receiving the Broadcast, given the above scenario.

Therefore option 'D' seems more plausible.

one up for A. The answer choices are very confusing. It's important not to lose focus.

I just want to point out choice D talks about all radio programming. The conclusion only discusses special programming. Hopefully that should make it quicker and easier :)

Re: Radio stations with radio data system (RDS) technology [#permalink] New post 18 Nov 2013, 07:07
I was slow on this (4 min), but the answer should be A.

1) ID question type: Find the Assumption.
2) Deconstruct the Argument:

- RDS is only received by special RDS radios.
- '94 to '96: RDS stations increase from 250 to 600.
- # of RDS radios in the the country same in '96 as '94.
- Conclusion: # of People in country who receive RDS signals did not increase.

Logic gaps in the argument: Just because someone owns an RDS radio doesn't mean he can receive the signal (maybe he's not in range of a station?). If he was out of range of a station in 1994 with an RDS radio living in the outback wilderness, but all of a sudden in 1996 a new station pops up on a mountain top nearby, then he would be able to listen. So we need to find something that assures us that all RDS owners in '94 had reception and can listen to RDS stations.

3) Remind yourself of the goal: Find the Assumption Question type.

4) Wrong from wrong to right (process of elimination):

a. Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

- Here I'm thinking that this one could be good. It's saying that few NEW stations built after 1994 were built in NEW areas...so that means that RDS coverage remains about the same in the country. It answers our logic gap above. I'll leave this one and analyze my other choices.

b. In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.

- This isn't really providing us with any important information to bridge the logic gap. In 1996, people in range can listen. Whoopty-do. Eliminate B.

c. Equipping a radio station with RDS technology does not decrease the station's listening area.

- So range doesn't change when a station has RDS technology. This doesn't matter as we are trying to bullet-proof our argument against whether or not the NEW stations reached NEW listeners. It doesn't deal with the new stations being built. Eliminate C.

d. In 1996 Verlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.

- Is this really telling us anything new? We already know that people without special RDS radios can't receive RDS signals. Eliminate D.

e. The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.
- Irrelevant. Who cares what they broadcast? It has nothing to do with reaching new listeners. Eliminate E.
