26. Business-method patents have recently aroused concern because of

　　[A] their limited value to business

　　[B] their connection with asset allocation

　　[C] the possible restriction on their granting

　　[D] the controversy over authorization

　　【其他答案】[D] the controversy over authorization

　　【点点答案】[C] the possible restriction on their granting

　　【解析】问商业方法专利最近由于什么引起了人们的关注。根据题干的recently我们定位到原文第二段。Now the nation’s top patent court appears poised to scale back on business-method patents, which have been controversial ever since they were first authorized 10 years ago. 答案就在这句话中。我们来看，这句话的意思是：现在美国顶尖的专利法院似乎谨慎地缩小商业方法专利，而这种专利自从10年前被政府授权后就一直存在争议。

　　至于某机构选择的[D] the controversy over authorization (对授权的争议)，从这句话的定语从句部分我们可以知道，这种争议已经长达10年之久，而不是现在才引起人们的关注，因此是不能入选的。我们选[C]the possible restriction on their granting(对他们授权可能的限制)，其中appear表示“看起来、似乎”= seem 替换选项中的possible(可能的)；scale back(缩减)替换 restriction。
