Question ID:PT68 S2 Q8 Passage: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 warming. They also conjecture that these microbes reproduce more quickly at higher temperatures. Stem:The scientists' conjectures, if true, provide the most support for which one of the following statements? Correct Answer Choice:CChoice A:The microbes' activity will soon diminish as the organic molecules in exposed sediments are depleted. Choice B:Every organism that generates carbon dioxide reproduces more quickly at high temperatures. Choice C:If global warming occurs, it will be exacerbated by the activity of the microbes. Choice D:The microbes do not remove any element other than oxygen from the atmosphere. Choice E:A significant portion of the carbon dioxide in Earth's atmosphere was produced by the microbes.
