   Every organism that generates carbon dioxide reproduces more quickly at

   The statements indicate that for at least one organism this relationship is true, but to say that it is true for every organism that generates carbon dioxide goes too far.

   If global warming occurs, it will be exacerbated by the activity

   Why this is right

   There is a runaway cycle that is possible given the statements. The microbes generate carbon dioxide, which promotes global warming. Since these microbes reproduce more quickly at higher temperatures, the more carbon dioxide in the environment, the faster the microbes reproduce and in turn again the more carbon dioxide is generated to promote global warming.

   The microbes do not remove any element other than oxygen from

   The scientists statements are conjecture and so cannot establish whether microbes have removed any elements other than oxygen. Furthermore, elements other than oxygen and carbon dioxide are not discussed in the statements.

   A significant portion of the carbon dioxide in Earth's atmosphere was produced
