Aging is a property of all animals that reach a fixed size at maturity, and the variations in life spans among different species are far greater as that among individuals from the same species: a fruit fly is ancient at 40 days, a mouse at 3 years, a horse at 30, a man at 100, and some tortoises at 150.
(A) among different species are far greater as that among individuals from
(B) among different species are far greater than that among individuals from
(C) among different species are far greater than those among individuals of
(D) between different species are far more than that between individuals of
(E) between different species are greater by far than is that between individuals from

Far greater than..Instead of far greater as. So answer should be from B,C,D.

Among should be used for more than two. So Among should be used here. So the answer should be from B and C.

Variations is plural. So those should be used instead of that. So C should be the answer.

In metalwork one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bonding, is effected continuously over a broad surface instead of a series of regularly spaced points with no bonding in between.
(A) instead of
(B) as opposed to
(C) in contrast with
(D) rather than at
(E) as against being at



I will go with D . A is wrong because X instead of Y my understanding is that X and Y have to be parallel.
B really doesnt fit in here.

the contact is effected continuously over a broad surface in contrast with a series of regularly spaced points with no bonding in between.

this looks like comparison of apples with oranges.

as against being is of course a wrong usage.

(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids
(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive
(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids


I guess its E. Between X and Y is the right usage. A and B are out.
C and D are verbose and "to produce" sounds better.

Convinced with Option-B.
Use of "of" in parallelism merge noun with the start of the parallels, and comma separated other parallels.

like should not be used to give examples, hence
(A), (C) - wrong
(E) convuluted in meaning and structure - shellfish is not even mentioned anywhere
(C) - "it" has no clear referrent
(B) - seems to be the best
- parallelism in terms of 3 actions: cultivation of crops, harvesting of ...,
exploiting of ...

But can preposition following subjects in a phrase be only based to relate parallelism..Okk. is it the gerund use of harvest?..I think it's used as such..I am convinced..
