Explanation
This question harks back to the prior question, in which
the culture and economy where mentioned to demonstrate that the less obviously
important innovations might still play an important role supporting the more
obviously important innovations. It's not uncommon for reading comprehension
passages to hammer on the same point. Answer choice (A) is out: no factors or
diversity of factors is discussed. (B) is correct: the author is in the middle
of an explanation about how innovations can't be judged easily according to the
practical definition. (C) is the opposite of the point; there isn't a clear link between the
definition and the impact on GDP. (D) and (E), similarly, describe what belongs
in the definition, but the point is that the definition is inclusive to a
fault.
The correct answer is (B).
