问题     Computer programs are unusual in that they are virtually the only products that have been protected both by patent and by copyright. Patents protect the idea behind an innovation, whereas copyrights protect the expression of that idea. However, in order to win either protection, the idea must be clearly distinguished from its expression.
    Which of the following can be properly inferred from the statements above?
选项 A、The idea behind some computer programs can be distinguished from the expression of that idea.
B、Anyone who writes a computer program is the inventor of the idea of that program.
C、Most products that are copyrighted are expressions of ideas that are patented.
D、Few inventors are owners of both patents and copyrights.
E、A patent for a computer program is no more difficult to win than a copyright.
答案A
解析 A选项和原文结论一致，正确。B项本文看不出写了程序的人和程序的思想是什么关系，不选。C项的意思就是大多数产品，既有专利保护又有版权保护。但是根据原文，计算机程序有这两种保护是很罕见的，因此该选项错误，不选。D项根据原文，程序员就有可能既是专利的拥有者又是版权的拥有者，不选。E项版权和专利的获取难度属于文章以外的信息，不选。
