Question

plz help thanks ((((((((:

Answer 1

Definitely the biography of a dog sledder. That is a real experience that can show how climate change could affect his/her experience of a dog sledder.
Wikipedia is not a trustful source, a novel may not explain real facts, and the new york times article could misrepresent information.

Answer 2

The correct answer to this question is letter "b. a new york times article." The most credible secondary source for research about the effects of climate change on eskimo villages is B). You shouldn't use wikipedia articles since you don't know if it is reliable.
Hope this helped!
