Academics in theology departments generally agree that there are fewer religious people today than fifty years ago. There are two primary critiques of that view, however. First, the conclusion depends on a definition that is highly subject to debate. If “religion” is defined as a strongly held conviction about the purpose of the world, for instance, the academics may be incorrect. On the other hand, the conclusion would be justified if "religion" is defined as a belief in a supernatural god. Second, the academics base their conclusion almost exclusively on data collected from the western hemisphere.
Which of the following, if assumed, strengthens the conclusion of the academics?
A) The definition of "religion" was as highly subject to debate fifty years ago as it is today
B) The conclusion applied only to the western hemisphere
C) Academics often draw conclusions based on evidence based almost exclusively on data from the western hemisphere
D) Most people believe "religion" should be defined as a belief in a supernatural god
E) Fewer people believe in a supernatural god today than fifty years ago
Don't understand how B is the answer. I thought B weakens.
