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. ffice ffice" />
(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
Choice A is incorrect on several grounds: greater as should be greater than, that should be those to agree in number with its referent, variations, and from should be of.
I have no idea when use "from" or use "of", could you please tell me the difference?
I appreciate your help
