Although a minority of researchers has pointed to certain high-altitude Andean valleys, where local records suggest slight cooling, a recent synthesis concludes that over the past several decades mean temperatures have risen more rapidly across the Tibetan Plateau than in surrounding lowland regions. Investigators have long hypothesized that several distinct mechanisms produce larger thermal excursions at high elevations than at lower ones. First, extensive portions of the plateau are mantled in snow and ice, which are strongly reflective; when that cover recedes, the newly exposed ground absorbs solar radiation and amplifies further warming. Second, the atmosphere at such elevations is rarefied, so comparatively little energy is needed to raise its temperature. Third, a smaller fraction of incoming solar energy is dissipated through evaporation at these cold, high altitudes than in the humid tropics.
Consider each of the choices separately and select all that apply.
The passage identifies which of the following as mechanisms that may generate substantial temperature variation at high elevations?
A. the proportion of solar energy dissipated through evaporation at high altitudes
B. the exposure of ground surfaces following the loss of snow cover
C. the rarefied character of the atmosphere at high elevations
In citing the apparent cooling in certain high-altitude Andean valleys, the researchers mentioned in the passage intend to raise which of the following as a question?
A. whether the Andes are less prone to extreme temperature shifts than are other high-elevation regions
B. whether those localized cooling records might point to a meaningful pattern that the broader warming average does not capture
C. whether the temperature trajectory in those Andean valleys might soon reverse
D. whether the mechanisms governing temperature change in those valleys differ from those operating elsewhere at high elevation
E. whether the Andes receive more snow and ice than do other high-elevation regions

Explanation
Consider each of the choices separately and select all that apply.
1. The passage identifies which of the following as mechanisms that may generate substantial temperature variation at high elevations?
The passage explicitly identifies all three as mechanisms that may produce greater temperature changes at high elevations.
A. Correct. The passage states that less incoming solar energy is dissipated through evaporation at cold, high altitudes than in the humid tropics. More energy remains available to warm the environment.
B. Correct. When snow and ice recede, the newly exposed ground absorbs solar radiation, amplifying further warming.
C. Correct. The atmosphere at high elevations is rarefied (less dense), so comparatively little energy is needed to raise its temperature.
Answer: A,B,C

Explanation
2. In citing the apparent cooling in certain high-altitude Andean valleys, the researchers mentioned in the passage intend to raise which of the following as a question?
Identify the key contrast, The passage states that:
-A recent synthesis concludes that temperatures have risen more rapidly across the Tibetan Plateau than in surrounding lowlands.
-A minority of researchers points to certain Andean valleys where local records suggest slight cooling.
The mention of cooling introduces a potential exception to the broader warming trend.
Evaluate the choices
-A. Whether the Andes are less prone to extreme temperature shifts - The passage doesn't compare the Andes' overall susceptibility to other high-elevation regions.
-B. Whether localized cooling records reveal a meaningful pattern missed by the broader average - Correct. The contrasting evidence raises the question of whether the overall conclusion accounts for important local variations.
-C. Whether temperatures in the valleys will soon reverse - The passage makes no prediction about future temperatures.
-D. Whether the mechanisms differ between the valleys and other regions - The passage discusses mechanisms generally but doesn't connect the Andean cooling to different mechanisms.
-E. Whether the Andes receive more snow and ice - The passage provides no such comparison.
GRE takeaway
When a passage mentions a minority view that contrasts with a broader conclusion, ask what uncertainty that exception introduces. Here, the point is not to predict future cooling or explain its cause. It's to question whether the localized evidence reveals a pattern that the broader warming trend might overlook.
Answer: B.
