This stamp is probably highly valuable, since it exhibits a printing error. The most important factors in determining a stamp’s value, assuming it is in good condition, are its rarity and age. This is clearly a fine specimen, and it is quite old as well.
The conclusion is properly inferred if which one of the following is assumed?
(A) The older a stamp is, the more valuable it is.
(B) Printing errors are always confined to a few individual stamps.
(C) Most stamps with printing errors are already in the hands of collectors.
(D) Rarity and age are of equal importance to a stamp’s value.
(E) Even old and rare stamps are usually not valuable if they are in poor condition.
EXPLANATION FROM Fox LSAT
Remember in
Brewster’s Millions, when Richard Pryor bought that super-rare stamp for a zillion dollars, the one with the accidentally-upside-down airplane on it, and
mailed a **** letter with it? That ruled.
Anyway, the facts here are 1) this stamp has a printing error, 2) a stamp’s value is largely determined by condition, rarity, and age, 3) this stamp is in fine condition, and 4) this stamp is quite old. Conclusion: This stamp is probably highly valuable.
I cultivate a super-skeptical voice inside my head, and I let it come out when I’m arguing with the LSAT. You should too. Here’s what mine sounds like: “Ehhhhh… what about rarity, dude? You mentioned that rarity is important, but then you totally skimmed over the part where you were supposed to tell me whether this stamp was rare or not. Yes I know that it has a printing error, which might
suggest rarity, but couldn’t they have accidentally printed a zillion of these things? Rarity is important (you said it yourself) so until you tell me whether or not there are a zillion of these things, then I am going to assume you are trying to bullshit me.”
We’re asked to make it so that the conclusion is “properly inferred,” which means “prove the conclusion.” To plug up the hole in the argument, the answer simply must deal with the rarity of this stamp. Nothing less will do.
A) This is nice, but irrelevant. We need to know about the rarity.
B) Okay, this proves that our stamp is rare. It does have a printing error, so if it’s true that stamps with printing errors are
always confined to a few individual stamps, then this bad boy must be rare. I like it.
C) No, who cares who owns what stamps. Irrelevant.
D) This might be true, but we needed to prove that this stamp is rare in order to complete the argument. This ain’t it.
E) No, **** off. We’re trying to prove that this stamp is valuable. This premise could only be used to prove that a stamp in poor condition is
not valuable. This is miles away from the correct answer.
We’re going with B, because it answers the skeptical voice inside my head.
