Conclusion This stamp is probably highly valuable, since Support it exhibits a printing error. ███ ████ █████████ ███████ ██ ███████████ █ ███████ ██████ ████████ ██ ██ ██ ████ ██████████ ███ ███ ██████ ███ ████ ████ ██ ███████ █ ████ █████████ ███ ██ ██ █████ ███ ██ █████
Summary
This stamp’s likely highly valuable. Why? It exhibits a printing error, is in good shape, and is quite old, and the most important factors affecting a stamp’s value, assuming it’s in good condition, are its rarity and age.
Missing Connection
The conclusion is that the stamp is probably highly valuable. According to the premises, we know, assuming that it’s in good condition, a stamp’s value is largely determined by its rarity and age. The stamp in the stimulus is old, but the argument doesn’t outright state that it’s rare. We can infer the argument’s conclusion if we assume that a stamp having a printing error is a rare trait.
8.
The conclusion is properly inferred ██ █████ ███ ██ ███ █████████ ██ ████████
a
The older a █████ ███ ███ ████ ████████ ██ ███
We know that the stamp is old and, as a result, more valuable. The correct answer choice must explain what having a printing error has to do with being rare.
b
Printing errors are ██████ ████████ ██ █ ███ ██████████ ███████
According to the premises, we know that age and rarity greatly affect a stamp’s value. If (B) is true, then the stamp in the stimulus is both old and rare, allowing us to infer that the stamp is likely highly valuable, which is the argument’s premise.
c
Most stamps with ████████ ██████ ███ ███████ ██ ███ █████ ██ ███████████
It doesn’t matter who owns stamps with printing errors. We want to know why we can conclude that the stamp in the stimulus is likely highly valuable.
d
Rarity and age ███ ██ █████ ██████████ ██ █ ███████ ██████
How important rarity and age are, relative to each other, in determining a stamp’s value is irrelevant. We know they’re the two largest factors for determining the value of stamps that are in good condition, so the correct answer choice must explain what printing errors have to do with a stamp’s rarity.
e
Even old and ████ ██████ ███ ███████ ███ ████████ ██ ████ ███ ██ ████ ██████████
Irrelevant. The argument isn’t about stamps that are in poor condition.
