Passage 33
Computers cannot accurately predict climate change unless the mathematical equations fed into them adequately capture the natural meteorological processes they are intended to simulate. Moreover, there are processes that influence climate, such as modifications in land use, that scientists do not know how to simulate. The failure to incorporate such a process into a computer climate model can lead the model astray because a small initial effect can initiate a feedback cycle: a perturbation in one variable modifies a second variable, which in turn amplifies the original disturbance. An increase in temperature, for example, can boost the moisture content of the atmosphere, which then causes further warming because water vapor is a greenhouse gas.
For the following question, consider each of the choices separately and choose all that apply.
1. The passage mentions which of the following as adversely affecting the accuracy of computer predictions of climate change?
A. Failure to allow for some of the processes that influence climate
B. Mathematical equations that do not accurately reflect natural phenomena
C. An overestimate of the role of feedback cycles
2. In the context in which it appears, “amplifies” (line 11) most nearly means
A. exacerbates
B. explicates
C. expatiates
D. adds detail to
E. makes louder
