问题 The first paragraph mainly______.
What benefit can the patent system offer when the patent expires?
选项 A、An increase in consumer well-being.
B、A reduced price for consumers.
C、Higher productivity.
D、The promotion of a desirable invention.
答案B
解析 本题是细节题。参见文中第3段：What are the benefits of the patent system? First，there is the increase in consumer well-being brought about immediately by a desirable invention．In 17 years，the patent monopoly ends，and a second souse of benefits arises．这段中列举了专利制度所带来的两个好处—发明为消费者带来的好处，以及专利过期后商品的低廉价格。题干问的是后者，即专利过期后对消费者带来的好处。
