Example Input: Article: In the past, American families tended to be quite large. Parents raising five or more children were common. Over the years, the size of the family has decreased. One reason for this is an increase in the cost of living. On the average, children attend schools for more years than they used to, making them financially dependent on their families longer. Moreover, children nowadays are better dressed and have more money to spend on entertainment. The parents usually take the responsibility for all the expenses. Meanwhile, families are less close than they used to be. More and more American mothers work away from home. The break up of the family occurs when the parents divorce. A lot of children in the U. S. live part of their young lives with only one parent. Broken families usually result in problems for children and parents alike. Children blame themselves when their parents separate. They grow up feeling unsettled as they are moved back and forth between parents. Usually one parent is responsible for raising the children. These single parents must care for the children's emotional and psychological needs while also supporting them financially. This is very demanding and leaves very little time for the parent's own personal interests. Single parents often marry other single parents. In this type of family, unrelated children are forced to develop brother or sister relationship. The situations of many American families today are not good. However, recent signs indicate that things are getting better. The divorce rate is declining. The rate of childbirth is rising. Perhaps Americans have learned how important families are.

Example Input: Article: What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist may be able to put the tooth back in for you, but you have to get to the dentist first.In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is put the tooth back into your mouth, or you could put it in milk.Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth.He tried putting teeth into milk, into water, and into cell-culture medium .He also tried, just drying the teeth in the open air.He used teeth that had to be removed from people's mouths for various reasons.The teeth were put into one of the solutions or stored in the air for one hour.Then cells from the root of the teeth were scraped-off the teeth.Dr.Courts and the others then studied how healthy these cells were. The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth.However, few people keep cell-culture medium handy at home or in school. The next best thing was milk.But Dr.Courts said that the best thing of all was to wash the tooth and put it right back into its socket in the mouth.For some people, though, this is just too painful or upsetting.So milk will do, until you get your tooth (and your mouth)to a dentist.
