Environmentalist: Pure bio-diesel is much more economical than impure bio-diesel, which is mixed with petroleum because pure bio-diesel is entirely petroleum-free, and the price of oil is predicted to rise due to the worldwide dwindling of oil reserves.
Chemist: I strongly disagree. Pure bio-diesel is an economical disaster compared to impure bio-diesel because due to its vegetable origin, bio-diesel is susceptible to mold.
Which of the following, if true, most strengthens the chemist's objection to the environmentalist's claim?
(A) Even before the rise in the price of oil, petroleum is more expensive than the vegetables used to manufacture bio-diesel
(B) Due to political factors, the government has decided to withdraw its subsidies of pure bio-diesel
(C) Environmentalists are trying to limit petroleum consumption in order to reduce toxic emissions into the earth's atmosphere
(D) Impure bio-diesel has more chances of creating problems in car engines, a fact which raises the costs associated with it
(E) Even the slightest concentration of petroleum is toxic enough to kill mold

Environmentalist says that pure bio-diesel is petroleum free and a rise in oil prices won't affect the economic value of pure bio-diesel. While chemist objects to this and says that pure bio-diesel is susceptible to molding hence an economic disaster. We need to strengthen this objection of chemist.
(A) Even before the rise in the price of oil, petroleum is more expensive than the vegetables used to manufacture bio-diesel ..doesn't answer why pure bio diesel is a bad. in fact it strengths environmentalist view
(B) Due to political factors, the government has decided to withdraw its subsidies of pure bio-diesel. we are not concerned about the government..out of scope
(C) Environmentalists are trying to limit petroleum consumption in order to reduce toxic emissions into the earth's atmosphere. again this out of scope as we are looking something that responds to molding.
(D) Impure bio-diesel has more chances of creating problems in car engines, a fact which raises the costs associated with it. it doesn't answer why impure bio-diesel is creating more problems
(E) Even the slightest concentration of petroleum is toxic enough to kill mold . correct one as it is answering why impure biodiesel is good as petroleum in it will kill the mold.

Environmentalist: Pure bio-diesel is much more economical than impure bio-diesel (BD + P) because the price of oil is predicted to rise...
Chemist: Pure BD is an economical disaster compared to impure BD because due to its (pure BD) vegetable origin, bio-diesel is susceptible to mold.
Which of the following, if true, most strengthens the chemist's objection to the environmentalist's claim?
to strengthen Chemist's objection we need to prove why Impure BD is better economically or why Petroleum is needed
(A) Even before the rise in the price of oil, petroleum is more expensive than the vegetables used to manufacture bio-diesel
- since petroleum is more expensive - so A strengthens the Environmentalist argument - Incorrect
(B) Due to political factors, the government has decided to withdraw its subsidies of pure bio-diesel - clearly out of context
(C) Environmentalists are trying to limit petroleum consumption in order to reduce toxic emissions into the earth's atmosphere
- this option says that petroleum consumption leads to enhanced toxic emissions - in a way its a strengthener to Environmentalist - but we need to say why Impure BD is economically better or why pure BD is economically bad
(D) Impure bio-diesel has more chances of creating problems in car engines, a fact which raises the costs associated with it
In a way strengthener of Environmentalist argument - Incorrect
(E) Even the slightest concentration of petroleum is toxic enough to kill mold - Correct - It exemplifies why we need to use petroleum or why we need impure BD - because it is more stable as the petroleum kills the mold.
