The idea that government
should regulate intellectual property through copyrights and patents is
relatively recent in human history, and the precise details of what intellectual
property is protected for how long vary across nations and occasionally change.

They reward creators for their labor, and they encourage greater creativity.
Both of these are empirical claims that can be tested scientifically and could
be false in some realms.
Consider music. Star performers existed
before the 20th century, such as Franz Liszt and Niccolo Paganini, but mass
media produced a celebrity system promoting a few stars whose music was not
necessarily the best or most diverse. Copyright provides protection for
distribution companies and for a few celebrities, thereby helping to support the
industry as currently defined, but it may actually harm the
A. Countries may differ in their efforts to protect it.
B. The author considers its protection well-grounded.
C. People believe its protection may benefit creators.
D. The history of its protection has not been long.

[单项选择]Imagine a world in which there was suddenly no emotion -- a world in which human beings could feel on love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive: knowing neither joy nor pleasure, anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world would lack rewards and punishments.
