Question 8 is based on the following reading passage.

After replacing his old refrigerator with a new, energy-efficient unit, Praveen\’s electric bills increased.

Each of the following, if true, contributes to an explanation of the increase mentioned above EXCEPT?

(A) The new air conditioner uses a smaller share of the electricity used by Praveen\’s home than did the old unit.
(B) Praveen\’s electricity costs increased by 15 cents per kilowatt-hour after he replaced his air conditioning.
(C) Praveen installed an electricity-intensive indoor tanning bed after he replaced his refrigerating unit.
(D) Soon after the new air conditioner was installed, Praveen adopted a child, doubling the size of his household.
(E) Following the installation of his new air conditioner, Praveen\’s neighborhood experienced a prolonged and severe heat wave, requiring heavy use of the new unit.


Answer: (A)

Explanation: Option (A), that does not explain the apparent paradox. That the new unit uses a smaller share of total electricity is consistent with its being more energy efficient.

It does not explain how his electric bills could have gone up despite his installation of the more efficient unit; all other answers provide possible resolutions of such apparent paradox.

So, option (A) is correct.
