Toxic bioaccumulation, a mining hazard induced by the mercury compounds transferred from unrefined cinnabar ore, presently afflicts 7 of every 10 workers in the Redstone Mine. A second mineral which occurs in the same environment, chalcedony, restricts the release of toxins from cinnabar ore. Mining chemists suggest spreading chalcedony in the Redstone Mine in order to preserve the surviving workers.

Which of the following, if true about chalcedony, provides the strongest evidence that the suggestion will be successful?

A It accumulates in deposits which are concentrated in the mineral veins where cinnabar is found.

B It can on some occasions stay inactive in mineral veins for almost five years before it begins to spread.

C It spreads through an environment more gradually than does cinnabar in most geological settings.

D It does not prevent a few common varieties of cinnabar ore from releasing toxins.

E It can occasionally damage fish populations by poisoning their gills.

Answer must be (A) for the highlighted errors in other options....

(B) Suggests Inactivity of the mineral , which is out of context.
(C) Spreading of minerals , not relevant and useful under the current context.
(D) Releasing toxins (Some variety) restricts the cope..
(E) Damaging fish population is out of scope..

This is straight A, let us take a look at the options:

B - weakens by stating that chalcedony stays inactive for 5 years i.e. it does not prevent the release of harmful chemicals for this period. We are looking for a choice that lends more credence to the fact that spreading chalcedony in that area would save the workers there.

C - if anything this weakens the conclusion by stating that chalcedony takes more time to spread and hence be effective.

D - this clearly weakens by stating that it does not prevent a few chalcedony varieties from releasing toxins hence workers could still be afflicted.

E - states a negative aspect of chalcedony but we are looking for an answer choice that would compel us to use chalcedony in that area.

A - is the answer as it strengthens the conclusion by strengthening the assumption that the author.
