问题 Business-method patents have recently aroused concern because of ______.
Which of the following would be the subject of the text?

选项 A、A looming threat to business-method patents.
B、Protection for business-method patent holders.
C、A legal case regarding business-method patents.
D、A prevailing trend against business-method patents.

答案A

解析 本题是主旨题。本文第二段首句就表明了全文主旨:现在本国的最高专利法院好像完全倾向于减少授予这种商业模式专利了。而“倾向于减少”的同义转化就是“潜在的威胁”。B项“保护商业模式专利持有人”与原文信息相反,排除;C项“一个案子”范围太窄,原文中提到了很多案件;D项的“prevailing trend”的意思是“盛行趋势”,而缩减这种专利只是有苗头,还没有形成趋势,故排除。
