Most household appliances use electricity only when in use. Many microwave ovens, however, have built-in clocks and so use some electricity even when they are not in use. The clocks each consume about 45 kilowatt-hours per year. Therefore, households whose microwave oven has no built-in clock use 45 kilowatt-hours per year less, on average, than do comparable households microwave oven is otherwise similar but has a built-in clock.

Which of the following is an assumption on which the argument depends?

(A) Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven.

(B) Microwave ovens with a built-in clock do not generally cost more to buy than microwave ovens without a built-in clock.

(C) All households that have a microwave oven also have either a gas oven or a conventional electric oven.

(D) Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.

(E) There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock.

(A) - reiterates the stimulus
(B) - information is irrelevant to the discussion
(C) - additional information to the stimulus - not helpful in addressing the issue at hand
(D) - stating that if an oven don't have a clock will not install one so - these ovens most likely to be less expensive than the oven's with the build in clocks. - tempting answer
(E) - Additional information to the stimulus - Not quite relevant.
I don't have the OA but I'm going with D. Wait for your responses. Gracias.

I go for D.

A: irrelevant
B: irrelevant we aren't concerned about actual costs of the microwave.
C: irrelevant we aren't concerned about gas stoves or other appliances.
We wanna know why the microwave will use less power.
E: maybe, but this doesn't help the conclusion explain that these non-built in clock microwaves will use less power.

A. Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven.--- it can't be true ! as it is comparing oven with non-oven.
B. Microwave ovens with a built-in clock do not generally cost more to buy than microwav
e ovens without a built-in clock.--- nothing could support this.
C. All households that have a microwave oven also have either a gas oven or a Conventional electric oven.---out of scope.
D. Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.--- i m giving this a chance cause others can't be an ans
E. There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock.--- out of scope

D it is .

Wow. This is a case of a problem using the "wordiest" language possible to describe simple concepts. In any case, the answer is definitely D.

No option other than D makes sense in this case.

Option A is although a restatement mentioned in the argument, when negated it shatters the conclusion.
Does this mean that the option that shatters the conclusion when negated does not work always to get to the right answer for Assumption questions?

Thanks in advance!

M answer will be D (Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.) as A,B,C are nor relative. But now a days all smart microwave oven comes with all of them features. Still i wanna know the answer. :-D

Which of the following is an assumption on which the argument depends?

Conclusion: Highlighted above.

(A) Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven. - Incorrect. Conclusion is about household who have microwaves with clock and without clock. This talks about households that do not have microwave at all.

(B) Microwave ovens with a built-in clock do not generally cost more to buy than microwave ovens without a built-in clock. - Incorrect. Again diverting from the conclusion. We have to focus on energy consumption.

(C) All households that have a microwave oven also have either a gas oven or a conventional electric oven. - Incorrect. Clearly, irrelevant.

(D) Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one. - Correct. If households whose microwave oven does not have a built-in clock also don't have a separate clock (which will be equivalent to MW with clock) as a timer then yes, the conclusion is valid. These households will consume less energy.

Negation: If these households whose microwaves don't have clock have separate clock used as timer then the energy consumption of these households will be either same or more than households with microwave timer.


(E) There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock. - Incorrect. Conclusion is about energy and not about how many more house holds have microwave with clock.

Answer: (D).
