Guys,

Could you try the problem below? Please explain your answer.

S15-Q16. In response to mounting pubic concern, an airplane manufacturer implemented a program with the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division. When the program began in 1994, the division’s hazardous waste output was 90 pounds per production worker; last year it was 40 pounds per production worker. Clearly, therefore, charges that the manufacturer’s program has not met its goal are false.

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

A. The amount of nonhazardous waste generated each year by the passenger-jet division has not increased significantly since 1994.
B. At least as many passenger jets were produced by the division last year as had been produced in 1994.
C. Since 1994, other divisions in the company have achieved reductions in hazardous waste output that are at least equal to that achieved in the passenger-jet division.
D. The average number of weekly hours per production worker in the passenger-jet division was not significantly greater last year than it was in 1994.
E. The number of production workers assigned to the passenger-jet division was not significantly less in 1994 than it was last year.

E, it says that production workers assigned to the passenger-jet division are nearly equal as compared to 1994.

1994 hazardous waste - 90 pounds per production worker.

last year waste - 40 pounds per production worker.

Now denominator, which is nothing but the total workers, is nearly same for both the years

so to reduce the over all value ,numerator ,which is nothing but total waste in pounds should decrease.

B & E are close, but between the two i picked E for the reason same as above.

Thanks all for the explanations.

My pick was E. IMO is B. After I saw your explanations I am now more confident to say that the best answer should be E.

So, anyone who has some other thoughts regarding B, please post them.

The hazardous waste is per production worker...so it doesnt matter whether the no. of production workers increased or decreased.

B is the answer as it states that the no. of jets were the same in both years lending support to the conclusion.

I don’t have the OA since the source of is question is a GMAT Set. In this Set there is a referenced key for this question: B. I think “referenced keyâ€

Well i think both B & E are really close. Can anyone explain why one of them could be the best choice and why the other is not.

Javed.

B equates / talks about the number of airplanes made in the two years.

E talks about the number of production workers employed in the two years.

We need to make a judgement on whether the hazardous waste was lowered or not, and the only data we have relates hazardous waste to the number of production workers.

So B does not give enough information to make a judgement call, whereas E does.

I agree with you E's out there.

Another way to look at it is to negate each choice.

In E, if it had said that the number of workers were significantly more, the waste per worker would decrease
1000/100 -> 10
1000/10 -> 100 and weaken the argument
In B, if there were less jets produced relative to 1994, there would be less waste period. But we can't conclude that the waste per worker had reduced UNLESS you further "assumed" that the number of workers were the same or less

Straight E.

If you increase production workers from 10 to 1000, keep waste pounds same, pounds/worker obviously would be less.

Its E for me as well. An increase in the number of planes does not necessarily mean that there was an increase in the number of workers. So B is ruled out.

The number of workers does matters. If the number of workers has increased the waste output would have increased as well. Read the following :
In response to mounting pubic concern, an airplane manufacturer implemented a program with the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division.

Since the conclusion states that the program was sucessful the number of workers is less or equal to the number of workers in 1994. Hence E can be ruled out.

E is right . One needs to know the total number of workers in those two years for making a decision. That's why B is wrong.

let us take 100 workers in 1994
the total waste = 100*90 = 9000

last year let us take the workers = 100 again
amt of waste = 100*40 = 4000

4K is less than half of 9K, so goal met, but number of workers is not less. Hence E is ruled out

B it is
