Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verlanders receiving the special program information probably did not increase significantly.

Which of the following is an assumption on which the argument depends?

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.
B. In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
C. Equipping a radio station with RDS technology does not decrease the station's listening area.
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.
E. The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Since this questions seems to have confused people, let's try to break it down.

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verlanders receiving the special program information probably did not increase significantly.

Which of the following is an assumption on which the argument depends?

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.
b. In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
c. Equipping a radio station with RDS technology does not decrease the station's listening area.
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.
e. The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Assumption question: Find the conclusion. Find out which answer option is essential for the condition to be true.

Premises:
-Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.
- the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994

Conclusion:the number of Verlanders receiving the special program information probably did not increase significantly.

Even though new RDS radio stations have been set up, since the number of radios with RDS feature is same in 1996 as in 1994, the author is concluding that the same number of people are receiving RDS programs.

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.

So for his conclusion to be true, the author is assuming that RDS radio stations that began after 1994 did not broadcast to people who were unreachable previously. Hence answer A.

None of the other choices qualify as an assumption.

Thanks for the explanation. I also have trouble understanding the wording in answer choice A.

Can "Few if any" equal to "there maybe some"?

If there are some RDS radio stations that did broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations, doesn't it weaken this answer choice?

There is a distinction between:
Few - Very few
A few - Some
Few of my friends will go to the dance. (means very few or almost none of them will go)
A few of my friends will go to the dance. (means some of my friends will go)

So I would consider 'Few if any' to mean 1 or 2 if any at all... That number may not have enough impact to make a difference.

hi Karishma,
I am confused between A and D. I chose D because i thought about the case that people who dont have the RDS-equipped radios still can have chance to listen to programs brocasted by RDS radio stations (maybe through other people's RDS equipped radios), the situation which weaken the conclusion that "the number of Verlanders receiving the special program information probably did not increase significantly. "

The question asks for an assumption. (i.e. what is necessarily true to make the conclusion true?)
The gist of the argument is that since no. of radios is about the same, number of people receiving the RDS programming is also the same.

Option 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.

- Even if people without RDS equipped radios could access RDS programming (say on neighbor's RDS radio) in 1996, they could have done the same in 1994 as well. They could have received RDS programs from existing radio stations (using neighbors radio). The number of people receiving the programming then may not have changed. So the argument could still hold even if option (D) is false. It is not necessary for it to be true for the argument to be true. Then option (D) is not an assumption.

(At Veritas, we call this method Assumption Negation Technique (ANT). Assumption is something which needs to be true for the conclusion to be true. That is why it is called an assumption. If an option is negated and the conclusion could still hold, it is not an assumption)

On the other hand, if we negate option (A) and say that some RDS radio stations started broadcasting in areas which were not previously reached by RDS but where people owned RDS equipped radios, then the number of people receiving RDS increases in 1996 and the conclusion does not hold. Hence option (A) is the assumption.

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.

If the radios are not equipped with RDS, how could they get RDS programming? Do you mean using someone else's radio? Then my explanation above may help. If you mean that they could kind of install a software that supports reception of RDS on their radios (just taking a shot here!) or something, they could have done the same in 1994. How do you prove that the number of people receiving RDS programming has changed from 1994 to 1996? Only if you do that can you break the argument. _________________ Karishma Veritas Prep | GMAT Instructor My Blog Get started with Veritas Prep GMAT On Demand for$199

Thank you very much Karishma. Your explanation is convincing. Now i understand why D is inccorect now. hope i can learn the way you reason to eliminate incorrect answers of other assumption questions should any chance ever rise.
