Stimulus Summary
Norse settlers - Lived in Greenland from 900-1500
Inuit settlers - Lived in Greenland from at least 900-after 1500
900-1500 - Average temperatures dropped
Opposing point - The temperature drop caused the Norse to die out because Greenland was too cold for humans
Argument - The Inuit survived, so the temperature can’t explain the end of the Norse settlements
Answer Anticipation
The argument here is meant to rebut the opposing point - the claims of some people that the Norse settlements in Greenland died out because it became too cold for human habitation.
How does it rebut this claim? By showing an example of humans who inhabited Greenland at the same time, thus showing it wasn’t too cold for human habitation.
That’s a common method of reasoning - using a counterexample to disprove a point. Let’s find an answer describing that method.

Why choice B matches the stem
This answer is a fancy way of describing a counterexample. The claim being opposed is that the Norse settlements died out because Greenland was too cold for human habitation. The argument produces the evidence of the Inuit, who lived in Greenland at the time and thus prove that it wasn’t too cold for human habitation. Since this answer correctly describes the method of reasoning, it’s the correct answer. -
Cpresenting an alternative explanation Remaining source text redacted.
Why choice C is not credited
There’s no alternative explanation provided for why the Norse settlements disappeared. -
