Ecologist: The Scottish Highlands were once the site of extensive forests, but these
forests have mostly disappeared and been replaced by peat bogs. The common view is
that the Highlands’ deforestation was caused by human activity, especially agriculture.However, agriculture began in the Highlands less than 2,000 years ago. Peat bogs, which consist of compressed decayed vegetable matter, build up by only about one foot per 1,000 years and, throughout the Highlands, remains of trees in peat bogs are almost all at depths great than four feet. Since climate changes that occurred between 7,000 and 4,000 years ago favored the development of peat bogs rather than the survival of forests, the deforestation was more likely the result of natural processes than of human activity. In the ecologist’s argument the two portions in boldface play which of the following
roles?
A. The first is evidence that has been used in support of a position that the ecologist
rejects; the second is a finding that the ecologist uses to counter that evidence.
B. The first is evidence that, in light of the evidence provided in the second, serves
as grounds for the ecologist’s rejection of a certain position.
C. The first is a position that the ecologist rejects; the second is evidence that has
been used in support of that position.
D. The first is a position that the ecologist rejects; the second provides evidence in
support of that rejection.
E. The first is a position for which the ecologist argues; the second provides
evidence to support that position.

对于BOLDFACE题我就快疯掉了,天山做到第九了,这种题型就对一个,还是猜的,我晕,NN看点下小弟啊
其实，B选项我第一眼看到的时候，也没怎么搞明白是什么意思，但是读完ACDE的第一句话就会发现都不对的。
找到However的位置后，就知道作者要提出新的观点了，这是最重要的。
