Biodiesel is a fuel that can be used in most road vehicles instead of

the conclusion is "that many people care about reducing pollution" we need to prove that these drivers care about the conclusion

option A sounds fine so lets keep it
option B: this actually weaken the argument by stating a pro about gasoline and a con about biofuel
option C: does nothing also it specifically talks about "new cars" which doesn't really help
option D: this is out of scope and maybe kind of weakens by trying to introduce other entities into the argument .... these types of choices are common to divert us... eliminate
option E : reducing gasoline imports may benefit the economy however we are only concerned about the benefits the argument can bring to pollution and environment and "NOTHING ELSE"

option A: is correct as it shows that the drivers already care about reducing the pollution therefore they drive less which benefits the environment... now with bio diesel they would be happy and can drive as much as they want to

AS per me answer is 'C'.

the question wants to strengthen the argumetn, not the conclusion.
the argument is, as biofuel reduces pollution. when it is widely available, more cars will use it. but why?? because govt is going to make mandatory reducion in pollution..

what do you think??

C weakens the argument, the argument wants us to find an option that conveys " people in their own interests are willing to switch from gasoline to bio diesel, resulting in low level of pollution".. whereas C is trying to convey that because of government regulations, people are forced to switch... What C does is weakening the argument...

A and B are very close...

IMO B doesn't weaken the argument. It would actually strengthen the argument if it stated that biodiesel will cost 10%-20% more over the next decade or so. In that case, it would imply that instead of more cost people will use bio coz they care about pollution. However, B only states the present price and doesn't indicate what would happen when bio becomes widespread.

I will go with A.

Answer is B.

A) Many individuals try to minimize their driving in order to reduce pollution. This is NOT CORRECT. This somewhat strengthen the argument but not the most. Lets look for the second one.

B)Biodiesel fuel costs 10% to 20% more than gasoline. Even-though the price is of Biodiesel is higher then gasoline, still people will use Biodiesel, which proves that people care about reducion pollution. Doesn't matter, the price is higher, people gonna still use it. If this true, most strengthens this argument.

Answer: B
