Explanation
This question gives us another mind-reading exercise, one
that, even more than others, might sound at first like it compels us to understand
the psychology of M. Norton Wise. We must remind ourselves that, even if we
don't know the truth about the psychology of Wise, the answer choices have
objective differences. This question is slightly more difficult in that the
correct answer is not compelled by the need to avoid contradicting the passage
as directly as in other questions. Choices (A) and (B) both have some degree of
plausibility, because they describe factors that would aid Wise in the act of
explaining. So we can come back to those. Choices (C) and (E) both imply
unsupported claims; we have no knowledge that the calorimeter was a turning
point in chemistry and physics, or that Kuhn's theory easily can explain the
calorimeter. So those two are out. Choice (D) has a certain perfection: it
says, in a way, that Wise choose the example of the calorimeter to explain his
theory because the calorimeter was a fitting example. We can see that (D) is
superior to (A) and (B) through a kind of negation test. Suppose we wanted to
contend that the example of the calorimeter did not establish Wise's theory? Choice (D), if negated, would support
our contention: the calorimeter, in fact, was not developed by two scientists
with differences in view, for whatever reason. Such a fact would damage Wise's
explanation and bolster our contention. (A) and (B)
have no such material connection to Wise's argument.
The correct answer is (D).
