CR from Acro

by Giorgio » Sat Feb 06, 2010 8:42 am
Bio diesel is a fuel that can be used in most road vehicles instead of gasoline. Its use produces significantly less air pollution, Market research predicts that as this fuel becomes more widely available over the next ten years or so , hundreds of thousands of drivers will use it . We can only conclude , then, that many people care about reducing pollution.

Which of the following , if true , most strengthens this argument?

A) Many individuals try to minimize their driving in order to reduce pollution.

B) Bio diesel fuel costs 10% to 20% more than gasoline.

C) New environmental laws may require a reduction in amount of pollution new cars produce.

D) A significant amount of air pollution comes from sources other than automobiles.

E) Increased use of bio diesel will reduce the need to import gasoline form other countries.

Which of the following , if true , most strengthens this argument?

A) Many individuals try to minimize their driving in order to reduce pollution.
Correct : This provides support to the conclusion that many ppl care about reducing pollution.

B) Bio diesel fuel costs 10% to 20% more than gasoline.
Incorrect : Cost is not the issue here. Pollution is the issue.

C) New environmental laws may require a reduction in amount of pollution new cars produce.
Incorrect : Amount of pollution that new cars emit is irrelevant to the scope of the argument.

D) A significant amount of air pollution comes from sources other than automobiles.
Incorrect : Issue is not about other sources of air pollution.

E) Increased use of bio diesel will reduce the need to import gasoline form other countries.
Incorrect : Import-Export is out of scope.

I too belong to A camp.

We are told to strengthen the conclusion - many people care about reducing pollution, only option A shows that people are conscious about pollution and so they prefer to reduce driving to cut pollution.

B, in fact, weakening the conclusion, in that its trying to focus the usage of Bio diesel by people mainly to save cost. People don't care about pollution but for cost and so they are using the Bio Diesel.

Q stem says - most strengthens this argument? Do u think something fishy here..argument or it should have been conclusion ?

I am between A and B.

A- This clearly states that many individuals try to minimize their driving in order to reduce the pollution.

B- This actually strengthens the conclusion by proving that though the price of Bio-diesel is greater than that of gasoline, people on the survey say they will use it. This strengthens the conclusion that pollution concern is the reason.

Please help me in reasoning out why B is incorrect.

Correct : Though the cost has increased, people are ready to use the bio diesel fuel

C) New environmental laws may require a reduction in amount of pollution new cars produce.
Incorrect : Out of scope.

D) A significant amount of air pollution comes from sources other than automobiles.
Incorrect : Out of scope.

I agree,

A adds nothing to the argument, it doesn't address bio diesel at all.

B is indeed correct as it clearly eludes to the fact that although this new Bio diesel will be more expensive than traditional fuels people are still willing to use it. Hence they are indeed concerned about its only other benefit. i.e. Better for the environment.

B my pick...

Option shows motivation for reducing the pollution...(people choosing the biod even with the costs being higher)..

"A" may be eliminated only becuase there is no BioD link with the reduced usage....

As correctly indicated by outreach brother, this is the only reason why B superior to A

Reduction in the number of drivers --does not mean that pollution will be less.

It is highly possible that "one driver uses 2 or more cars" instead "one driver using only one car"

so pollution will increase or remain the same what it is now --- rules out

Answer is naturally B ;)

Premise 1 : Bio diesel produces less pollution.
Premise 2 : research shows that many people will use it as it becomes widely available.
Conclusion: Many people care about reducing pollution.

Now imagine, despite being widely available, if bio diesel's price is more /gallon or /liter than gasoline and still, people are buying it. How will you justify the extra-spending ? They want their vehicles to pollute less.

which lends support to the conclusion :

=> many people who are buying bio-diesel care about reducing pollution.

Harsha
