Read the Following Scenario and Answer the Question Below

Read the following scenario and answer the question below.
Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase the levels of carbon dioxide, methane, and nitrous oxides in our atmosphere. Measurable warming of Earth due to these greenhouse gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can lower levels of sea ice and increase precipitation in arctic areas. Global warming also can increases sea surface temperatures, which can subsequently melt permafrost in the tundra and increase the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species ʺout-of-sync,ʺ potentially causing indirect loss of species.
-Some models of climate change for North America predict that the grassland regions of the prairie states will become warmer and dryer. This would result in ______________.

A) a shift from grassland toward chaparral and savanna
B) less stress on groundwater and aquifers to irrigate crops in the area
C) increased damage from crop pests and diseases
D) the need to develop varieties of agricultural crops that tolerate desert conditions
E) the need to plant temperate deciduous forest trees to shelter crops from the sun
