swallow 15,000 tons of aspirin, one of the safest and most effective drugs
invented by man. The most popular medicine in the world today, it is an
effective pain reliever. Its bad effects are relatively mild and it is
cheap. For millions of people suffering from arthritis, it is
the only thing that works. Aspirin, in short, is truly the 20th-century wonder
drug. It is also the second largest suicide drug and is the leading cause of
poisoning among children. It has side effects that, although relatively mild,
are largely unrecognized among users. Although aspirin was first
sold by a German company in 1899, it has been around much longer than that.
Hippocrates, in ancient Greece, understood the medical value of the leaves and
tree bark which today are known to contain salicylates, the chemical in aspirin.
During the 19th century, there was a great deal of experimentation in Europe A. aspirin can be dangerous B. aspirin is always safe C. aspirin has been around a long time D. aspirin should be forbidden to apply to children

alone, almost as many as in the recession year of 1991. Yes,
unemployment went down. But over 1 million workers were so discouraged they left
the labor force. More than 6 million who wanted fun-time work were only
partially employed; and another large group was either overqua A. Over 1 million. B. 3 million. C. Over 6 million. D. 7 million.

son hanged himself during his winter break from the University of Arizona five
years ago, Donna and Phil Satow wondered what signs they had overlooked, and
started asking other students for answers. What grew from this
soul searching was Ulifeline (www. ulifeline, org), a Web site where students
can get answers to questions about depression by logging on through their
universities. The site has been adopted as a resource by over 120 colleges,
which can customize it with local information, and over 1.3 million students
have logged on with their college ID’s. "It’s a very solid Web
site that raises awareness of suicide, de-stigmatizes mental illness and
encourages people to seek the help they need," said Paul Grayson, the director
of counseling services at New York University, which started using the service
nearly a year ago. The main component of the Web site is the
