Explanation
Correct answer: B.
Choice B is the best answer. “Indicator” means “something that shows or suggests,” which matches Taleb’s argument that an item’s age can suggest how much longer it will last.
Why the other choices are wrong
Choice A
Choice A is incorrect. The passage tells us that examining an item’s age is the best way to predict how much longer it will last. Therefore, according to Taleb’s theory, an item’s age should add more certainty about how much longer it will last.
Choice C
Choice C is incorrect. A “motivation” is “a reason for doing.” Items don’t have feelings and motivations, so it wouldn’t make sense to say that their age is a motivation for how much longer they will last.
Choice D
Choice D is incorrect. “Criticism” can mean “describing faults or problems” or “an analysis of an artistic work.” Neither of these definitions makes sense here. An item’s age can’t criticize how much longer it will last.
