17. The primary purpose of the passage is to
(A) explain the differences in the working of a heat pump when the outdoor temperature changes
(B) contrast the heating and the cooling modes of heat pumps
(C) describe heat pumps, their use, and factors affecting their use
(D) advocate the more widespread use of heat pumps
(E) expose extravagant claims about heat pumps as false
Now, if under certain conditions a heat pump puts out more thermal energy than it consumes in electrical energy, has the law of energy conservation been challenged? No, not even remotely
Hope this helps: E was the less trickiest among all the answer choices.

Sorry I still did not get why E is incorrect over B. Please explain below 2 questions.
1. does "Extravagant claims" refer to advertisers claims? If so, doesn't the author trying to explain why the claim is wrong by bringing up role of evaporator in order to falsify 1 electric energy = 2 thermal energy?
2. For my understanding of answer choices, B more likely demonstrates structure of the passage than E, which concludes the passage.
Can you comment on this? I cannot figure out on my own.
Thank you in advance.

1) extravagant claim refers to the fact the passage conveys fancy and improbable twist to the law of energy and the author of the author says: no. You (someone) are trying to disrupt the law itself but your (someone) assertions do not have strong points
2) B is just part of the passage which explain how heat pumps work. It does not grasp the overall sense or idea of the passage.

Oh I am sorry. By mentioning B, I was actually pointing C.
It might be confusing, so let me be rectify my second answer again.
Answer choice C is more likely about structure of the passage and E seems concluding passage. I failed to pick C over E, so please clarify difference between answer choice C and E. What made me fall into this?
