Does anyone have a proper explanation to this question ?
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.
There is no discussion in the stimulus about - microbes' activity will soon diminish or organic molecules in exposed sediments are depleted. Incorrect (B) Every organism that generates carbon dioxide reproduces more quickly at high temperatures.
There is nothing mentioned in the stimulus about organism other than certain microbes. So Every organism in this choice makes it wrong.(C) If global warming occurs, it will be exacerbated by the activity of the microbes.
This option hints that if global warming occurs, it will be worsen by the activity of the microbes. So this is pretty good choice. Let's HOLD ON.(D) The microbes do not ren1ove any element other than oxygen from the atmosphere.
There is nothing mentioned here about removing an element other than oxygen. This choice is wrong again.(E) A significant portion of the carbon dioxide in Earth's atmosphere was produced by the microbes.
No data point mentioned in the stimulus in this regard.This choice is also wrong.Hence C is the Ans.
Hope this helps.
