问题 Business-method patents have recently aroused concern because of ______.
Which of the following is true of the Bilski case?

选项 A、Its ruling complies with the court decisions.
B、It involves a very big business transaction.
C、It has been dismissed by the Federal Circuit.
D、It may change the legal practices in the U. S.

答案D

解析 本题是判断题。定位点在第二段尾句:It "has the potential to eliminate an entire class of patents."这句话的意思是:这一案件有可能导致取消一整个种类的专利。正与D项“这个案子可能改变美国的法律实践”语义相同。A项中的“法庭裁决”不是在关于这个案子的叙述中提到的词汇,属于张冠李戴信息;B项曲解原文含义,原文说“这个案子非同小可”,B项说这个案子涉及一个很大的商业交易,属于偷换概念;C项原文根本未提,属于新信息。
