I think I have a way to explain this question, and you guys could tell me if I got this question right.
So, we can say, here are two store, Bj's and costco. Bj's has coupons, costco doesn't. They all have products, A, B, C, D, E.
COSTCO price: A $100 B $100 C $100 D $100 E $100
BJ's have same price as costco without distributing coupons. However,
"...without reducing profit, retail stores must pass it on to consumers"
&
"... on certain products charge more for their products, on average, than other retail store charge for the same products..."
Bj's have coupon for product A, so prices for these products could be:
A(the one has coupon) $1 B$100 C$200 D$200 E$200
let's see answers,
A) consumers could save a lot if they ONLY buy PRODUCT A, the one has coupon. OR, they can spend more if they buy all products. We can not infer "many save a little". All consumers could save a lot or spend more. WRONG
B) "... by charging higher prices for certain products" YES! If average is higher, there must be at least one product coming with a higher price. As shown above, Product C D E have higher price. Let's keep it for now.
C) "... not significantly lower, on average, than..." the profit could be more than other store. Shown in example upthere. Meanwhile, "...without reducing profit, retail stores must pass it on to consumers", we can infer that the profit is not reduced. WRONG.
D) We can not infer anything about stores that do not use coupon. WRONG.
E) "...charged for a good for which a retail store offers a coupon..." hmm... as shown above, Product B has a same price in two store. The stem says "...charge more for their products, on average, than other retail store ..." which doesn't mean EVERY good has a higher price. WRONG.
I didn't get this question right for the first time, because
for answer C, All I thought is, that, since store is gonna pass the expense to consumers, the profit couldn't be significantly lower, but I didn't think about profit could be more.
for answer E, it says "...charged for a good for which a retail store offers a coupon..." I thought " a good" here means a certain good, not EVERY good. So I choose E at first. After reading discussion above, I realise that " a good" here means every good, which is def wrong.
Am I thinking this question right? So in LSAT, some general term, like "a good" here, means every and can apply to all elements?
