Consumer advocate: A recent study concluded that top-loading washing machines are superior overall to front-loaders. But front-loaders have the controls and access in front. This is more convenient for wheelchair users, some of whom find it highly inconvenient to remove laundry from top-loaders. So for some consumers front-loaders are superior.

Which one of the following is an assumption upon which the consumer advocate’s argument depends?

(A) For some consumers the convenience of frontloaders outweighs the advantages of toploaders in assessing which is superior.
(B) Washing machines of a given type should be compared only with washing machines of that type.
(C) Convenience is the only important factor in determining which type of washing machine is superior.
(D) Retrieving clothes from a top-loader is convenient for people who do not use wheelchairs.
(E) Retrieving clothes from front-loaders is inconvenient for people who are not wheelchair users.

A is not an assumption, but just a restatement of what has already been stated in the passage. At most it could be an inference. An assumption should link the premise and conclusion. Option A does not do so.

C is better than A.The premise is about convenience, and the conclusion is about superiority. Option C links convenience with superiority. The word "only" is required because if there were other features that determine superiority then the conclusion that more convenient machines are superior cannot be drawn .

OA has been changed.

After reading through the options once, it seems B,D,E can be ruled out as they are not a necessary assumption.

For me it was a bit tough to choose between A and C, and A definitely seems more apt. C is a contender because it felt like for some users, main factor to determine superiority is convenience. But this is wrongly understood, as it seems to say that the main factor is convenience. But it doesn't have to be so, argument just implies that for some users, although there are other important advantages, convenience outweighs them all.

A recent study concluded that

If it is saying about overall superiority.There must be multiple factors. Hence C is not correct.
i.e
(C) Convenience is the only important factor in
determining which type of washing machine
is superior.

From your post it seems that you are confused between inference and assumption. I have already clarified the issue. Yet I shall try once again to explain (taking your point into consideration).

You have INFERRED that there must be multiple factors since the conclusion is about overall superiority. Thus your point FOLLOWS from the conclusion. The following arrow diagram explains the difference between an assumption and an inference:

1. Premise ------- (Assumption) --------> conclusion
2. Premise / conclusion / other information in the passage ---------> inference

Your point falls under the second category above and hence is an inference.

Now once again consider the reasoning in the given passage:

Premise: X is more convenient than Y.
Conclusion: X is superior (/overall superior) to Y.

Link: Convenience is the only factor to determine the superiority (/overall superiority).

Whether you consider overall superiority or superiority, the premise is the same that X is more convenient. Thus C is the correct option.

Hi Sayantan, Don't you think 'C' is too strong? The argument actually assumes that 'Convenience is a criteria of superiority for a particular group of people(Wheel chair users in this case)'. But the argument does not even hint that convenience is the only criteria of superiority. With that we did not know 'why top-loading washing machines are superior overall to front-loaders?'. Whether that is for convenience to all other group of users. Actually I do not think that this might be a GMAT question. What do you think? GMAT may ask this type of question?

Whether that is for convenience to all other group of users. Actually I do not think that this might be a GMAT question. What do you think? GMAT may ask this type of question?

It does not matter whether the scope of the premise is for one particular group of users or all the users. In either case the explanation given above holds. (If the premise is applicable for a particular group, the conclusion is also applicable for that particular group). Let me try once again to elaborate my explanations above:

The concept of "too strong" is applicable only for inference type questions, not for assumptions. In assumptions "too strong" statements are required to eliminate any possibility of alternative cases.

Take this general example:
Premise: X and Y happen together (scope: one particular group of users)
Conclusion: X causes Y (scope: only that particular group of user)

Strengthening statement: Some other event Z does not cause Y
Assumption: NO other event causes Y ( or in other words ONLY X causes Y).
(Both the above types are limited to the particular scope considered in premise and conclusion.)

In the subject question:
X= convenience
Y = superiority
The scope is limited to particular group of users.

If the question were a strengthening type question then a statement similar to the following could be answer:
Price is not an important factor in determining superiority. (Price = Z)

Since the the subject question is an assumption type question, the following statement is a correct answer:
Price or any other factor except convenience is not important in determining superiority. (for a particular group of users)
or in other words,
Convenience is the only factor in determining superiority. (for a particular group of users)

A IMO ;
Here isn't it taking a particular group "for some consumers"to say something about universal in C ?.

A is an inference, not an assumption. Rather A is just a restatement of what has already been given in the passage.

However for option C, you are right. Ideally in option C it should have clarified that the statement is only about the particular group in question. In a real GMAT test, this kind of omission is probably not expected.

This bold text is the conclusion.

Assumption must be shatter proof meaning even if there is one case where the conclusion wont hold it breaks the conclusion. Hence we must make sure the underlying assumption is fool proof.
The conclusion says that based on convenience people decide which is superior. What if there is another factor which along with convenience decides which is superior.
In that case the entire argument falls apart. Hence assumption must be the exact opposite i.e., to say there is no other factor than convenience that decides which is superior. Hence C

as for D ,it is just an inference that needn't be true. Negating it doesn't do anything to the argument. Remember Assumption is an unstated premise that links the premises and the conclusion.

Hope I am clear.

VKat, as explained by goforgmat, choice D does not need to be true...

Quote:
(D) Retrieving clothes from a top-loader is convenient for people who do not use wheelchairs.

According to a recent study, "top-loading washing machines are superior overall to front-loaders." This suggests that many users find top-loaders superior in many ways (ie perhaps most users find that top-loaders clean their clothes faster and more thoroughly than front-loaders do). This does not require that most users find top-loaders to be superior in EVERY way. In fact, most users may find that "retrieving clothes from a top-loader" is actually INCONVENIENT; however, those users can still view top-loaders as superior to front-loaders overall based on other factors. Thus, D is not necessary.

This is a question from Manhattan LSAT. And the official answer is "A". Please correct the OA.
Below explanation has been mentioned in one of the forums of Manhattan website.

Answer choice is (C) is actually the sufficient assumption, as the truth of answer choice (C) would guarantee the conclusion. But it's not necessary that convenience is "the only" important factor. It's simply too strong...

OA - A

Conclusion - For some consumers front loaders are superior

Negating C- Even if Convenience is the not the only important factor in determining which type of washing machine is superior, the conclusion can be true. For some people, it's just a more important factor (A).

Imo C
The author is classifying washing machines based on convenience.
Hence C is the necessary assumption

Hi,

I feel, had the choice C read as "For some consumers, convenience is the only important factor in determining which type of washing machine is superior", it would have been an apt choice. I feel "only" is making it too strong.

Thanks
