Automobile emissions

by bhumika.k.shah » Thu Feb 04, 2010 1:10 am
Automobile emissions are a significant source of air pollutants, and cars over five years old typically generate significantly greater amounts of pollutants than newer cars. In Torinia, which has recently built its first automobile manufacturing plant, most cars are over five years old. Aiming to boost Torinia's economy and reduce air pollution, the government plans to introduce incentives for Torinians to scrap their old cars every five years and replace them with new ones.

Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims?

(A) Without the implementation of the planned incentives, most Torinians who own an old car would be unlikely to buy a new car.
(B) Torinia's automobile plant manufactures car models that typically generate smaller amounts of air pollutants than most similarly sized car models manufactured elsewhere.
(C) The new cars produced in Torinia are not likely to be exported to other countries.
(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.
(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants.

Shouldn't both the aims be achieved since its using 'and'

(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.
(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants

Stem: Find an answer which undermines the likelihood that "economy boost" and "less pollution" cannot be achieved using incentives.


Premises:

1. Automobile emissions are a significant source of air pollutants
2. cars over five years old typically generate significantly greater amounts of pollutants than newer cars
3. Torinia has recently built its first automobile manufacturing plant
4. Most cars in Torinia are over five years.

Using these premises it can be concluded that if incentives are given then, old cars will be replaced, reducing pollution and since new cars are bought, the business of the manufacturing unbit will prosper and economy gets a boost.

So something has to be found out that will not lead to pollution reduction and economy boost. However, one thing should be remembered that economy factor is dependent on the buying of new cars which will take place only if the old cars are scrapped due to reason of pollution. Incentive will help buying of new cars which will reduce pollution and hence trigger the economy.


PoE:


(A) Without the implementation of the planned incentives, most Torinians who own an old car would be unlikely to buy a new car.

Out of Question. You have to find where the two benefits wont be achieved when incentives are used.

(B) Torinia's automobile plant manufactures car models that typically generate smaller amounts of air pollutants than most similarly sized car models manufactured elsewhere.

Thats good. It shall be a factor which shall reduce pollution and if incentives are there, people will buy and would boost the economy. But we are looking for a factor which shall undermine the likelihood that the two things can be achieved. This strengthens and not weakens the success of incentivizing.

(C) The new cars produced in Torinia are not likely to be exported to other countries.

How does it affect the success of incentivizing. If nothing better, it strengthens as most cars will be sold in Torinia after incentives.

(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.

Let it be the largest. There is no comparison here. We want to reduce air pollution and elimination is not practically possible. This is out of scope as it does not emphasize what happens if incentives are given. However, premise say that it is significant contributor, largest or not does not matter.

(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants.

If this happens, the aim of lessening the air pollution wont be satisfied as significant amount of air pollution is caused in both old cars as well as manufacturing of new cars and scrapping of old cars. The argument states as premise that
"cars over five years old typically generate significantly greater amounts of pollutants than newer cars". But if the procedure in this transition leads to same amount of pollution, why will people even think of changing their cars even if there are incentives. They are not going to receive the cars for free. These are just incentives. Since government expects that people can help in reducing pollution, they provide incentives. And if new cars are not purchased then there is no point boost in economy.

Answer is E.

Both the aims should be achieved, but here one aim depends on other and hence the primary aim is reducing air pollution as supplemented by the premise. This is the most suitable option.

Wow!
nice explanation :)

U got patience to write all this :)

I too chose E

But while picking one answer choice i was just wondering that the aim is specifically A and B.
So is it okay if we are fulfilling or in this case weakening just one part of the aim.??

not thinking any further on this topic i chose E . Since it was better than all the remaining choices.

:D

Thanks!

Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims?
Aim 1 : Boost Torinia's Economy
Aim 2 : Reduce Air Polution
Our Aim : To Find An Answer Choice That Most Seriously Undermines Both The Aims

(A) Without the implementation of the planned incentives, most Torinians who own an old car would be unlikely to buy a new car.
Incorrect : This will neither reduce pollution nor boost economy. Does not undermine Aim 1 or Aim 2 or Both. Eliminated !

(B) Torinia's automobile plant manufactures car models that typically generate smaller amounts of air pollutants than most similarly sized car models manufactured elsewhere.
Incorrect : ------- Same as (A) ------ >>>>>> Goes in the trash bin !

(C) The new cars produced in Torinia are not likely to be exported to other countries.
Incorrect : Import-Export of Torinian Cars is not an issue here.

(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.
Incorrect : Largest source v/s Significant Source?????? Eliminated !

(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants.
Correct : Clearly undermines both aims. Manufacturing + Scrapping both will generate air pollution. Hence it will not help to boost economy (manufacturing) nor will it help in reducing pollution.

I still feel E should be the answer.
