Happy to help. The author is arguing that the idea of consumption isn't sufficient for explaining economic well being. The author provides the example that humans get very little satisfaction from knowing that various products get consumed.
We're looking for what the author is arguing. We know that the author is trying to say that consumption is insufficient for explaining economic well being.
(C) says, "Aboriginal communities should be granted full protection of all of their customs."
(A) is supported by the second sentence in the stimulus that deals with clothes wearing out, automobiles depreciating, and gas burning up.

Thus, (A) is the correct answer, as it's supported by the stimulus and highlights what the author is arguing.
Hope this helps. Let us know if you have any other questions!
