Business travelers are time-sensitive travelers. They know that the

I do agree and thought on same lines for eliminating options A,C and E. However, I have chosen option 'B' and my logic behind eliminating option 'D' is:
D- There are no advantages that check-in baggage allows over carry-on baggage that are of any use to business travelers.
Even if there are some advantages that check-in baggage allows, for time sensitive business travelers, there is no reason to think unless there is some reduction in waiting time

Business travelers are time-sensitive travelers. They know that the collection of check-in baggage is always slow and one wastes precious time waiting for it. Therefore, business travelers avoid check-in baggage.

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

A- Carry-on baggage is more comfortable to carry and business travelers seek comfort more than other travelers

B- The travelers who choose to check-in one’s baggage is neither time-sensitive nor a business traveler.

C- Carry-on baggage is similar to check-in baggage in terms of size, weight allowance, and other restrictions.

D- There are no advantages that check-in baggage allows over carry-on baggage that are of any use to business travelers.

E- Carry-on baggage is free whereas check-in baggage needs to be paid for.

negating the main point:
BT will carry check-in bags
given that a) BT are time sensitive b)check-in wastes lot of time

pre-think:
what if the check-in bag is of some advantage than anything else

look at the options:
A- Carry-on baggage is more comfortable to carry and business travelers seek comfort more than other travelers
even if carry on bags are more comfortable, so will be others since it is not given particularly that it is the most comfortable way. hence loose ends. hence incorrect

B- The travelers who choose to check-in one’s baggage is neither time-sensitive nor a business traveler.
traveler is either of time sensitive or BT. this implies, in both case it will not carry check-in bags. hence its opposite

C- Carry-on baggage is similar to check-in baggage in terms of size, weight allowance, and other restrictions.
even if carry-on bags are similar to check-in it can imply they can carry either of the two. again loose ends. incorrect

D- There are no advantages that check-in baggage allows over carry-on baggage that are of any use to business travelers.
there are business related benefits on carrying checkin, hence it defines the specific related reason i.e. business.
hence no further argument!. hence correct.

E- Carry-on baggage is free whereas check-in baggage needs to be paid for.
even if not free, no idea who can pay or who cannot pay. loose ends. hence incorrect

This is confusing. Here the argument is that business travellers want to save time. Conclusion is that hence business travellers do not checkin their luggage. I think the assumption is that there is no other reason why these travellers check in their baggage. I mean what if business travellers like to use some of the stuff in the baggage during the flight, maybe that is why they avoid checkin luggage. Or what if the business travellers believe that their luggage gets mishandled if they check-in. Basically the assumption is that there is no other DISADVANTAGE of checkin luggage other than the time factor mentioned. Or carry over luggage provides no advantage over check in luggage. What is mentioned in Option D is reverse of that.

If we go via negation method which should negate the argument, we say that there are advantages of checkin baggage and still business travellers chose to check in their luggage. That means that they are really considerate of their time and hence this would strengthen the argument.

B is a better choice.
Negate choice B:The travelers who choose to check-in one’s baggage is either time-sensitive or a business traveler.-->This breaks the argument.Hence is an assumption.

First of all the argument never mentions anything about carry on baggage.So,we cannot say that BT prefer Carry on Baggage.

Other advantages do not matter.... D cannot be the answer choice...

My thinking aligns with that of yours.

Option D cannot be correct

It basically says THAT CHECKIN BAGGAGES DONT HAVE ANY ADVANTAGE, and if this is so then this could be the reason why they don't choose it irrespective of time.

C has to be the correct answer.
Because if we negate C and say that check-in baggage have more restrictions or they allow less weight then the argument will collapse.

VeritasKarishma GMATNinja when i negate B - i get travellers who chose to check-in one’s baggage is either time-sensitive or a business traveler- which breaks conclusion apart
Then why b is not the answer

This is testing defender assumption logic. I am pretty sure D. was the intended choice, but the ordering of check-in vs carry-on luggage is reversed in choice D.

I too thought similarly and eliminated D.

If the option said 'no other advantages' then it wold be the correct answer IMO.

Hello,

Good to see so many users using the correct approach and reasoning in getting to the correct answer choice.

There should ideally be no controversy about the correct answer choice. The mistakes that some of the users on this thread are making are as follows....

0. Not identifying the conclusion correctly; the conclusion is that "business travelers avoid check-in baggage" and not that "business travelers avoid check-in baggage because they are time-sensitive"; that they are time-sensitive is a premise, not a part of the conclusion.

1. Biggest mistake: Assuming that "time sensitivity" is the "only trait" of business travelers; logically, there are bound to be other factors that must affect their choices. Such basic mistakes happen when, rather than logical reasoning, we over-apply the concepts we read in books.

2. Applying ANT incorrectly; after negation, choice D must become that "there are serious other useful advantages...for business travellers". Now think, if there are serious other advantages, isn't the argument weakened?
2.1 Applying ANT to begin with; keep this as a back-up option; this is time-consuming and not full-proof and needs to be applied carefully; else, it may lead to selection of some very hasty choices (B in this case, as sleected and passionately debated by many users on this thread).

3. Not seeing the howler in option B! Mistake on the lines of point 1 is in fact in answer choice B as, apart from being an extreme and hasty choice, it takes the context to non-business travelers!

Humble suggestion: When you disagree with something, please ask yourself "what am I missing?", rather than concluding a source incorrect; that is the correct approach to learn.

Here is a concise video explanation-

Answer is D because the conclusion that Business travellers avoid check-in baggage is based on the premise that the same baggage is time-consuming. Assumption between the premise and conclusion is that with carry-in baggage, travellers do not need to wait in queue and waste time.

The argument is that b-travelers avoid check-in baggage.

This is based on the fact b-travelers are time-sensitive and know that collection is always slow as one wastes precious time waiting.

We are asked for assumptions.

A- The argument is only concerned with avoiding check-in due to time sensitivity (premises) so we can't really assume anything to do with comfort.
B - This may or may not be true. As such, it is wrong.
C - Same as B.
D - This is the only relevant assumption to business travellers. The premises indicate that business travellers are time sensitive and thus prioritise time saving measures (carry on only) over delays.
If we negate D - there are some advantages that check-in offers to business travellers, then it weakens the argument that b-travelers should avoid check-in completely.
E - we can't really assume this. It may or may not be free.

but the question does not talk about carry on baggages

Thanks for the explanation; however i think that if choice D were
D. There are no advantages that carry-on baggage allows over check in baggage that are of any use to business travelers.

then it would have made more sense, this choice will tell that only time is the main factor while choosing the carry on, time saving is also the main reason given in the argument.

Even if there is any advantage that check-in baggage offers, how can we assume that business travellers are ready to give up "time-saving" advantage for the check-in baggage? Since the argument talks about the reason why business travelers avoid check-in baggage, this part of the evidence is required. The goals of two baggages are different. One is to save time and the other is to provide any other advantage, but not time-saving.

This goal switch is not mentioned in option D. Highly doubtful.

I can have the advantage of traveling on a train - cheap cost of travel. Also, I can have another advantage of traveling by a car - comfort and self-decided journey breaks. This itself doesn't justify which one shall I opt for. Another part is required - I am ready to go the cheaper fair while sacrificing my comfort. Only then I can establish the reason why I avoid traveling by a car.

I have a tough time eliminating option C - what if the restrictions etc are different for carry-on & check-in baggages? For example: carry-on baggage must have <5 kg weight, whereas there is no such weight limit in case of check-in baggage. How can a business traveler use carry-on baggage if the weight of his baggage is 20 Kgs? Would this not weaken the argument that business travelers should use check-in baggage only?

Request your opinion and clarification. I understand the Option D, but not completely convinced with why option C is wrong.
