More hopeful experts claim that food production will change very little because there is little reason to expect altered rain distribution even with climatic changes. For most crops, annual fluctuation and agricultural technology mask yield changes due to climate. The more hopeful claims are based on which of the following assumptions?
A) Technology is so influential that regardless of climate, improved yields are unlikely.
B) Climate changes cannot be predicted with accuracy.
C) Temperature trends are more predictable than rainfall trends.
D) Cooling trends threaten food production more than warming trends.
E) Climate changes would be more damaging if rainfall patterns are coupled with them. The answer is E , why?作者: mike1999 时间: 2003-7-27 19:06
