Members of the VideoKing Frequent Viewers club can now receive a special discount coupon. Members of the club who have rented more than ten videos in the past month can receive the discount coupon only at the VideoKing location from which the member last rented a movie.

If all of the statements above are true, which one of the following must be true?

Must  Be True

(A) The only people who can receive the special discount coupon at the Main Street location are Frequent Viewers club members who have not rented more than ten videos.

Frequent Viewers club members who   have   rented more than 10 videos can go receive the special discount at the location of the last rented movie. Their last rented movie could be located at the Main Street location. Eliminate.

(B) Some members of the Frequent Viewers club have not rented more than ten videos.

We have no evidence that this must be true. Eliminate.

(C) Some members of the Frequent Viewers club can receive the special discount coupon at more than one location of VideoKing.

We have no evidence that this must be true. Eliminate.

(D) Some people who are not members of the Frequent Viewers club can receive the special discount coupon.

Pat used the special discount. She has not rented more than 10 videos. She can use the discount at a location other than Main Street. So she has an exception to those two rules. Therefore, she must not be in the Frequent Viewers club.

(E) If Pat rents a movie from the Main Street location, then she will not receive the special discount coupon.

We have no evidence that this must be true. Eliminate.

Hi  EducationAisle   GMATNinja , can you help me with this one. The argument says 
1.   Members of the VideoKing Frequent Viewers club can now receive a special discount coupon  .
2.   Pat, who has not rented more than ten videos in the past month, can receive the special discount coupon

Doesn't 1 and 2 imply Pat is a member of "Frequent Viewers club"? Although I think I know where I might be wrong with this one, cause 1 does not says   Only   Members of the VideoKing Frequent Viewers club can now receive a special discount coupon, but if we construct a sentence like Members of A club will get a discount. Pat will get a discount. Can it be inferred that Pat is a member of the club?

HoneyLemon · Answer

As is common in Must Be True questions, this stimulus contains conditional reasoning. The author sets out the rules for members of the Frequent Viewers club to obtain a special coupon. If the member has rented more than ten movies in the last month, they can only obtain the coupon at the store from which they last rented. If they rented ten or fewer, they can only obtain the coupon from the Main Street location. From these facts, we can derive two separate conditional rules:
  Sufficient ..... ..... ..... ..... Necessary

More than ten ..... ---> ..... Coupon at store from which they last rented

Ten or fewer ..... ---> ..... Coupon only from Main Street

The stimulus then provides the information that  Pat, who has rented fewer than ten movies, can obtain her coupon at Walnut Lane. Immediately, we can see a problem. The conditional rules above state that if Pat rented ten or fewer movies, he can only obtain the coupon  the Main Street store. This apparent conflict  is the key to the question,  and it is worth the time to figure out what additional information is present in the stimulus. On a closer read, we discover that the conditional rules only apply to those in the Frequent Viewers club. If Pat is not in Frequent Viewers club, the conditional rules above would not apply.

Answer choice (A): This is a mistaken reversal. The conditional rule states that the if the member rents ten or fewer movies, they must get the coupon from the Main Street store, but it does not say the only people who can get the coupon there are members of the Frequent Viewers club with ten or fewer rentals.

Answer choice (B): Even though the stimulus sets out rules for how members of the Frequent Viewers club who rent ten or fewer movies can get the coupon, it does not say that there are any members of the Frequent Viewers club to whom the rule would apply. We do not know anything about the members of the club. We only know the rules of the club, and information about Pat.

Answer choice (C): This answer choice must be false. Either members of the club will have rented ten or fewer videos, in which case they must get the coupon from Main Street, or they will have rented more than ten videos, in which case they must get the coupon from the store from which they last rented. The conditional rules mean that members of the club can only get the coupon from a single specific location.

Answer choice (D): This is the correct answer choice. As discussed above, Pat’s situation did not fit into either conditional rule. The only way that she could have rented ten or fewer movies, and received her location at a store other than Main Street, is if she was not a member of the Frequent Viewers club. This must mean that non-members can also receive coupons.

Answer choice (E): The rules do not tell us anything about when people cannot get coupons; it only gives information about when members can get coupons. As with any Must Be True questions, any answer choice that lacks support in the stimulus is incorrect.

I think by now you might have understood why Pat is not a member .

Just a recap:
1. Members of the VideoKing Frequent Viewers club can now receive a special discount coupon. 
2. Members who have not rented more than ten videos in the past month can receive the coupon  only  at the Main Street location. 
3. Pat, who has not rented more than ten videos in the past month, can receive the special discount coupon at the  Walnut Lane location of VideoKing.

So I assumed Walnut Lane location IS NOT a Main Street location.

Make it simple:
1. Members receive a coupon
2. If less than 10 , received  only  at MS.
3. Pat get at other location --> so definitely Pat is not a member ( because of presence of  only )

Now you can visualize how  only  limits the scope.

Now back to your question: 
Members of A club will get a discount. 
Pat will get a discount.

Can it be inferred that: Pat is a member of the club
Answer: NO 
 
Why?
I make some modifications you can see why:
case1: 
Members of A club will get a discount. 
Pat will get a discount.

Can it be inferred that: Pat  MAY B E a member of the club
Answer:  YES

Case2:
 ONLY  Members of A club will get a discount. 
Pat will get a discount.

Can it be inferred that: Pat is a member of the club
Answer:  YES

We need to understand the scope of the statements . Literally stick to that scope and strike off whatever doesn't come in that scope.
Key point:  Only  makes the scope very restricted. without only , the scope is open :  may  or may not

I hope you get the point.

You're on the right track!

The passage tells us that members of the club CAN get the coupon. That doesn't mean that they are the ONLY people who can get the coupon.

The people in the club fall into two categories: either they've rented more than 10 videos, or they haven't. If they've rented fewer than 10 videos, then they can ONLY get the coupon at the Main Street location.

Our friend Pat comes along. She's rented fewer than 10 videos. So, if she were a member of the club, then she could ONLY get the coupon at Main Street.

Weirdly, Pat gets the coupon at a different location. From this, we can infer that Pat is NOT in the club, and she still got the coupon.

So, it  must be true  that people who are NOT in the club can get the coupon. And (D) is the correct answer.

I hope that helps!

Even after reading the passage 10 times, I thought that   Walnut Lane location of VideoKing  must be the  Main Street Location ? Only after reading the explanations, I realized it's not that difficult to figure out the correct answer ONCE what exactly the argument is conveying is understood well!

How to improve comprehension skills? Is it that the language in the passage is tough, or it is natural for a reader to get lost as this passage does sound a bit ambiguous wrt different names?

Foreheadson · Answer

Hi GmatNinja,

Thanks for the explanation. But I still struggle to understand the following:
Members of the Frequent Viewers club who have not rented more than ten videos in the past month can receive the coupon only at the Main Street location.
Members of the Frequent Viewers club who have not rented more than ten videos in the past month can  only  receive the coupon only at the Main Street location.

These don't seem equivalent. Maybe the case is that members who have not rented more than 10, can receive discount at main. But maybe there is another unstated condition that these same members can get discount somewhere else. without that word "only" the logic still seems obscure.
