Most geologists believe oil results from chemical
transformations of hydrocarbons derived from
organisms buried under ancient seas. Suppose,
instead, that oil actually results from bacterial action
on other complex hydrocarbons that are trapped
within the Earth. As is well known, the volume of
these hydrocarbons exceeds that of buried organ-
isms. Therefore, our oil reserves would be greater
than most geologists believe.

Which of the following, if true, gives the strongest
support to the argument above about our oil
reserves?
(A) Most geologists think optimistically about the
Earth's reserves of oil.
(B) Most geologists have performed accurate chem-
ical analyses on previously discovered oil
reserves.
(C) Ancient seas are buried within the Earth at
many places where fossils are abundant.
(D) The only bacteria yet found in oil reserves could
have leaked down drill holes from surface
contaminants.
(E) Chemical transformations reduce the volume of
buried hydrocarbons derived from organisms
by roughly the same proportion as bacterial
action reduces the volume of other complex
hydrocarbons.

I would go with E. If E is true, it gives support to the conclusion of the argument "Therefore, our oil reserves would be greater
than most geologists believe. "

E is only relevant.

X generates oil by doing A
Y generates oil by doing B
Since X is more available, more oil comes through X

One valid support is X and Y burn/generate at the same rate

E it is

Since both hydrocarbons are reduced to same proportion and since the volume of complex hydrocarbons is more E gives the result.

(E) Chemical transformations reduce the volume of
buried hydrocarbons derived from organisms
by roughly the same proportion as bacterial
action reduces the volume of other complex
hydrocarbons.

I would go with E because to start with the volume of these hydrocarbons exceed that of buried organisms. E talks about the reduction of volumes by the same amount but to start with the Vol of HC is > Vol of Org
Not sure if this is the right way to look at the argument or not.

By POE, E is the most relevant. A, B and C are out right away.

Using POE, I would choose E

But it's not really clear to me why it's E.

Could someone provide an explanation ?
