GRE Exam Verbal Ability Miscellaneous

Question 1 is based on this passage.
Extensive housing construction is underway in Pataska Forest, the habitat of a large population of deer. Because deer feed at the edges of forests, these deer will be attracted to the spaces alongside the new roads being cut through Pataska Forest to serve the new residential areas. Consequently, once the housing is occupied, the annual number of the forest’s deer hit by cars will be much higher than before construction started.

Question 1
Which of the following is an assumption on which the argument depends?
(A) The number of deer hit by commercial vehicles will not increase significantly when the housing is occupied.
(B) Deer will be as attracted to the forest edge around new houses as to the forest edge alongside roads.
(C) In years past, the annual number of deer that have been hit by cars on existing roads through Pataska Forest has been very low.
(D) The development will leave sufficient forest to sustain a significant population of deer.
(E) No deer hunting will be allowed in Pataska Forest when the housing is occupied.

(A) a check on
(B) an advocate for
(C) an impediment to
(D) a brake on
(E) an apologist for
(F) an intermediary for Questions 1 and 2 are based on this passage.
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.

Question 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
