Scientists conjecture that certain microbes consume organic molecules in exposed shale and similar sediments. In so doing, the microbes remove oxygen from the atmosphere and generate carbon dioxide, a gas that, evidence indicates, promotes global wanning. They also conjecture that these microbes reproduce more quickly at higher temperatures.

The scientists' conjectures, if true, provide the most support for which one of the following statements?

(A) The microbes' activity will soon diminish as the organic molecules in exposed sediments are depleted.
(B) Every organism that generates carbon dioxide reproduces more quickly at high temperatures.
(C) If global warming occurs, it will be exacerbated by the activity of the microbes.
(D) The microbes do not ren1ove any element other than oxygen from the atmosphere.
(E) A significant portion of the carbon dioxide in Earth's atmosphere was produced by the microbes.

Only option C is valid option.

(C) If global warming occurs, it will be exacerbated(worsened) by the activity of the microbes.

as indicated in the passage (remove oxygen from the atmosphere and generate carbon dioxide, a gas that, evidence indicates, promotes global warming.)

so if global warming is already happening microbial activity will add to the cause.

I narrowed down to C and E.
E says a significant portion but no where in the argument it is mentioned that a major Amount of CO2 is produced by microbes,therefore E is out
ans C

IMO C

All other options look extreme.
