问题 Gingrichian politicians reluctant to address the problem because______.
The new findings about global climate change are based on______.

选项 A、new data
B、the virtual models
C、lab experiments
D、scientists’ observation

答案B

解析 本题是细节题。参见文章第2段:This shift in scientific consensus is based not so much on new data as on improvements in the complex computer models that climatologists use to test their theories.这一段话介绍了气候学家用来证实理论推测的方法—利用复杂的电脑模拟系统,创造出模拟的大气环境,而非通过所掌握的大量的新数据。
