[字彙] 兩題邏輯請教
A spacecraft traveling through the solar system's main asteroid belt, which
lies between Mars and Jupiter, transmitted images of two asteroids, Iole and
Thetis, Thetis has significantly more impact craters--marks left by collisions
with neighboring asteroids--than does Iole. Hence, Thetis is significantly
older than Iole.
Which of the following, if true, provides the most support for the argument?
(A) Not all impact craters such as those found on Thetis and Iole are of the
same depth and shape.
(B) Many asteroids that have been identified by the images transmitted by
spacecraft are not located in the parts of the solar system's main
asteroid belt in which Iole and Thetis are located.
(C) The asteroids that make up the solar system's main asteroid belt are not
as old as either Mars or Jupiter.
(D) Both Thetis and Iole are of a type of asteroid that is formed when a
collision breaks up a larger asteroid.
(E) The asteroids in the part of the asteroid belt where Iole is located are
more likely to collide with each other than are those in the part of the
belt where Thetis is located.
這題我覺得五個選項都無法支持這篇短文的論點阿
為什麼(E)可以支持呢? 謝謝

The crustacean known as harpacticoida are very widespread in marine
sediments, where they feed on microorganisms by ingesting the sediment
particles to which the microorganism adhere. Heavy metals, such as those found
in industrial pollution, readily adhere to sediment particles. Harpacticoids
are poisoned by heavy metals but are unaffected by most other pollutants.
Therefore the concentration of harpacticoids in an area is a good indication
of whether that marine environment contains heavy metals.
Which of following is an assumption on which the argument relies?
(A) Industrial pollution is the principal source of heavy metals in
marine sediments.
(B) Harpacticoids are the only crustaceans that feed on microorganisms by
ingesting sediment particles.
(C) Harpacticoids are more susceptible to poisoning by heavy metals than are
other marine organisms.
(D) The microorganisms that harpacticoids feed on are not killed by pollutants
that are harmless to harpacticoids.
(E)The microorganisms that harpacticoids feed on absord heavy metals.
這題一樣不懂為何(D)是答案
麻煩高手解惑了
謝謝
