Difficulty:


In the past most airline companies minimized aircraft weight to minimize fuel costs. The safest airline seats were heavy, and airlines equipped their planes with few of these seats. This year the seat that has sold best to airlines has been the safest one - a clear indication that airlines are assigning a higher priority to safe seating than to minimizing fuel costs.

Which of the following, if true, most seriously weakens the argument above?

(A) Last year's best-selling airline seat was not the safest airline seat on the market.
(B) No airline company has announced that it would be making safe seating a higher priority this year.
(C) The price of fuel was higher this year than it had been in most of the years when the safest airline seats sold poorly.
(D) Because of increases in the cost of materials, all airline seats were more expensive to manufacture this year than in any previous year.
(E) Because of technological innovations, the safest airline seat on the market this year weighed less than most other airline seats on the market.

weight is the key here ...E pointed out that weights of safe seats were reduced ---> even they buy more heavy seats, the total weigt of seats may be less ----> lower fuel costs.
E it is.

The core point we've to be warned if airlines are interested with minizing fuel cost or not nowadays.

The choice E says that safety seats will induce minimizing costs because they weighten less than the other seats which in turn will lead airlines to minimize fuel costs.

I have chosen E for this question:

The conclusion is: [highlight]This year the best selling seats to airlines have been the safest one, indicating that airlines are more concerned about safety than fuel costs.[/highlight]

The question stem looks for an answer choice that will weaken the argument.

A. This answer choice would support the argument.

B. This is a tricky answer. The problem is that although no airline company has announced a higher priority for safe seating, this does not mean that airlines are not doing so. They could be choosing not to announce this and internally making a decision to re-prioritize.

C. This would support the argument. The reason is because if the price of fuel is higher this year, that means costs will be higher. Since airlines are still buying these safe seats that are heavy, it would suggest that the airlines care more about safety than fuel costs.

D. This is irrelevant. We are not concerned with the increase in the cost of materials.

E. This is the correct answer. The reason is because since the safest seats are also the lightest, there is no CLEAR INDICATION that airlines are buying these seats because of safety. Airlines could be buying these seats because of the reduction in fuel costs.

Conclusion: Airlines are assigning higher priority to safe seats than to minimizing fuel costs
Premise: Safest seats are the ones best sold to the airlines this year.

Assumption: Safest seats do not minimize fuel costs. i.e. safest seats are not lightweight. Undermine this assumption.

Alternatively, negate the conclusion and select answer choice that supports the negated conclusion along with the premises.
Negated conclusion: Airlines are not assigning higher priority to safe seats than to minimizing fuel costs

Type - weaken
Boil it down - In past the safest airline seats were heavy. This year the seat that has sold best to airlines has been the safest one - a clear indication that airlines are prioritizing safety over costs .
Pre-thinking - what if the safest seats are the lightest ones now .

(E) Because of technological innovations, the safest airline seat on the market this year weighed less than most other airline seats on the market - Correct answer

Which of the following, if true, most seriously weakens the argument above?

(A) Last year's best-selling airline seat was not the safest airline seat on the market.
Out of scope of the argument because best selling seat are not discussed directly but it means that the airlines did not prefer the safests seats.

(B) No airline company has announced that it would be making safe seating a higher priority this year.
The airlines do not neccesarily make announcments to make changes in planes.

(C) The price of fuel was higher this year than it had been in most of the years when the safest airline seats sold poorly.
Does not weakne but partially strenghten by aking a point about the fuel price.

(D) Because of increases in the cost of materials, all airline seats were more expensive to manufacture this year than in any previous year.
(E) Because of technological innovations, the safest airline seat on the market this year weighed less than most other airline seats on the market.
The premise says that the safe seats are heavy, and the heavy seats makes the plane burn more fuel,the airline wants to save money by saving fuel.
Conclusin says that the seats were removed because they were the heaviest.but still the airlines use them to prioritize saftey
This choice says that the new safest seats were also the lightest,that proves that the airlines are just saving fuel not prioritizing the saftey.

================================================================================================
Weakener CR:The link between the premise and the conclusion has to be attacked more than anything,and the choice that does so pick that more than anything.
