多选题The origin of the theory that major geologic events may occur at regular intervals can be traced back not to a study of volcanism or plate tectonics but to an investigation of marine extinctions. In the early 1980's, scientists began to look closely at the question of how these extinctions occur. Two paleontologists, Raup and Sepkoski, compiled a master list of marine species that died out during the past 268 million years and noted that there were brief periods during which many species disappeared at once. These mass extinctions occurred at surprisingly regular intervals. Later studies revealed that extinctions of terrestrial reptiles and mammals also occurred periodically. {{U}}These findings, combined with the research of Raup and Sepkoski, led scientists to hypothesize the existence of some kind of cyclically recurring force powerful enough to affect living things profoundly.{{/U}} Speculation that so powerful a {{U}}force{{/U}} might affect geologic events as well led geologists to search for evidence of periodicity in episodes of volcanism, seafloor spreading, and plate movement. The passage suggests which of the following about the "force" highlighted in the passage? A. It is responsible for most of the major geologic events that have occurred. B. It is responsible for most of the marine extinctions that have occurred. C. Its recurrence is unlikely to be able to be predicted by scientists. D. Its existence was not seriously considered by scientists before Raup and Sepkoski did their research. E. Its existence was confirmed by the research of Raup and Sepkoski.

多选题The correlation between carbon dioxide and temperature throughout the Vostok record is consistent and predictable. The absolute temperature changes, however, are from 5 to 14 times greater than would be expected on the basis of carbon dioxide's own ability to absorb infrared radiation, or radiant heat. {{U}}This reaction suggests that, quite aside from changes in heat-trapping gases, commonly known as greenhouse gases, certain positive feedbacks are also amplifying the temperature change.{{/U}} Such feedbacks might involve ice on land and sea, clouds, or water vapor, which also absorb radiant heat. The author mentions "certain positive feedbacks" in order to indicate that A. increased concentration of carbon dioxide in the Earth's atmosphere is responsible for global temperature increase. B. some climate simulation models have produced useful information. C. greenhouse gases alone do not account for global temperature increase. D. variables that benefit life are causing global temperature to increase. E. beneficial substances that are not heat-trapping gases and that contribute to global temperature increase have been found in the Vostok ice core.
