Question Stats:
34% (02:35) correct
65% (01:58) wrong based on 10 sessions
If retail stores experience a decrease in revenues during this holiday season, then either attitudes toward extravagant gift-giving have changed or prices have risen beyond the level most people can afford. If attitudes have changed, then we all have something to celebrate this season. If prices have risen beyond the level most people can afford, then it must be that salaries have not kept pace with rising prices during the past year.
Assume the premises above to be true. If salaries have kept pace with rising prices during the past year, which one of the following must be true?
(A) Attitudes toward extravagant gift-giving have changed.
(B) Retail stores will not experience a decrease in retail sales during this holiday season.
(C) Prices in retail stores have not risen beyond the level that most people can afford during this holiday season.
(D) Attitudes toward extravagant gift-giving have not changed, and stores will not experience a decrease in revenues during this holiday season.
(E) Either attitudes toward extravagant gift-giving have changed or prices have risen beyond the level that most people can afford during this holiday season.
Can someone give detailed explanations for elimination or choice of an option?
Thanks

the answer must be C in my opinion. (C) Prices in retail stores have not risen beyond the level that most people can afford during this holiday season. If salaries have kept pace with rising prices during the past year, only the above mentioned statement follows, out of the given five.

Decrease in revenue ------------ (Change in gift giving Policy) or ( price that people can't afford)
( Retail Sales )
(Change in gift giving Policy)---------- ( festival season )
( price that people can't afford) ----- (Salary not in pace )
A----B-----D
A----C-----E
Correct Ans - E(Not) ---- C(Not)
Salary is in Pace ----- Price can be afford by people
Correct Ans - C)

If salaries have kept pace with rising prices during the past year, which one of the following must be true? so if salaries kept pace then retailers must not have risen the prices beyond... it has nothing to do with the change in the attitude  LSAT tends to puzzle us hope it helps

Thanks It can only be (C). A, D, and E all make the assumption that retail stores have experienced a decrease in revenue, but that is not a given piece of information - everything is IF there is a decrease in revenue. For B, you can't make that claim because there's another factor which could decrease revenues (attitudes about gift-giving have changed). You're left with C.

Thanks This question uses simple logic Here we have the condition if A then B If [prices have risen beyond the level most people can afford], then it must be that salaries have NOT kept pace with rising prices during the past yearNow if you apply negation to if A then B it becomes If Not B then Not A. (I learnt this in one of my deduction classes ) So the question stem says what happens in case of "Not B" [If salaries have kept pace with rising prices during the past year], see you dont have a not as the sentence in the question's last sentence had. Then in this case the answer should be Not A. Which means Not [prices have risen beyond the level most people can afford] Hence the answer has to be C.
