The average cable television company offers its customers50 channels,but new fiber-optic lines will enable telephone companies to provide 100 to 150 television channels to their customers for the same

In 1712 the governmentof Country Y appointed a censor to prohibit the publication of any book critical of Country Ys government;all new books legally published in the country after 1712 were approve

Under the first censor, one half of the book manus submitted to the censor were notapproved for publication.Under the next censor, only one quarter of the bookmanus submitted were not approved, but the number of book manus that were approved was the same under both censors.

Given how influential these media are, we have goodreason to believe that these depictions cause young people to engage
38、in violent behavior. Hence, depictions of violence among teenagers should be prohibited from movies and television programs, if only in those programs and movies promoted to young audiences.Maurice: But you are recommendingnothing shortof censorship!

Since 18-year-olds in the republic are generally either high school graduates or high school dropouts, the correlation leads to the conclusion that the republics recruitment rates for 18-year-olds depend substantially on recruitment rates for high school dropouts.Which one of the follow
