Complete Question Explanation
Weaken. The correct answer choice is (C)
Here the author begins by pointing out that to keep your hands warm, you don’t ever absolutely need
gloves or mittens. You can keep your hands warm by wearing a thermal undershirt or a sweater, since
keeping your vital organs warm can keep your hands warm as well. Putting the argument in a more
straightforward order:
You can keep your hands warm by keeping your vital organs warm.
Therefore you can keep your hands warm by wearing a thermal undershirt or sweater.
Therefore gloves or mittens are never an absolute necessity in keeping your hands warm.
The argument is followed by a weaken question stem, so the correct answer choice will effectively
attack part or all of the argument presented above.
Answer choice (A): The author makes no claims about which part of the body it is more important to
keep warm, so this answer choice has no effect on the argument presented.
Answer choice (B): The author presents no information about the best type of layering for keeping
warm, so this choice plays no role in the argument and thus cannot weaken.
Answer choice (C): This is the correct answer choice. If wearing an extra layer of clothing does
not, at certain temperatures, keep your hands warm, then this disproves the premise that you can
always keep your hands warm with an extra layer of clothing.
Answer choice (D): The author does not claim that wearing an extra layer of clothing is the best
way to keep warm—only that it is one effective way to do so. Even if turning up the heat is more
effective, this does not weaken the author’s somewhat limited claim about wearing an extra layer.
Answer choice (E): There is no suggestion in the stimulus that the warmth is derived in the process
of putting on an extra layer of clothes, but rather that wearing an extra layer can be an effective way
to keep warm.
