Political science professor: many people insist that the internet is revolutionizing the political process. they argue that internet debates and online political polls and chat rooms give people greater access to political information. and they’re right that online political chatter increases daily. but offering or reading anonymous online opinions does not by itself make for active political participation. in the past one would attend a rally, protest, or town meeting to engage in real politics. today, people sit passively in front of computer screens under the illusion that they are connecting with their fellow citizens.
which one of the following best expresses the main idea of the professor’s argument? (points : 1)

a. internet debates and online political polls and chat rooms give people greater access to political information.
b. political organizations of the past bear no resemblance to the political organizations of today.
c. while the internet has made more political content available, meaningful political involvement has decreased.
d. the internet has revolutionized the political process because it has allowed many more political viewpoints to be expressed.
