Article: Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health. In a new study, the researchers found that pizza is a large source of calories, saturated fat and salt in children's diets.Children should not eat more than two slices of pizza for a meal,and should pair that with salad, rather than with another high-calorie food,the researchers concluded. "Parents should aim to control pizza consumption , particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands."Said Lisa Powel, director of the Illinois Prevention Research Center. Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them.Studies have found pizza is among the greatest sources of calories for children. "Since pizza remains a common part of children's diet, we need to make 'healthy' pizza."Powel said.To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content," she said. Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. "Many foods are eaten too frequently and in large sizes," said Tindall.To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza,"she said. "Make it at home, instead of ordering it out where you don't have any control over how it's made." Tindall said. "When we make it at home, we can choose healthier ingredients,increase the vegetables, reduce fat, and put in less cheese.Pizza doesn't have to be just pepperoni and cheese."

Read the following article and select the best answer. Article: While it may be unlikely for a computer to write a best seller, a technology expert has created a computer program that writes its own fiction stories with minimal user input. The program, called MEXICA, is the first to generate original stories based on computerized representations of emotions and tensions between characters. An Internet survey was carried out to see the popularity of the computer-generated stories, other computerized stories and stories written solely by a human. The result was that readers ranked MEXICA stories highest for flow and coherence, structure, content, suspense and overall quality. Rafael Perezy Perez, the creator of MEXICA, explained that a story might begin with something as basic as, "The enemy wounded the knight. The princess cured the knight. The knight killed the enemy. The knight rewarded the princess. The end." The program reads characters as variables and assigns a numerical value, between a continuum from -3 to +3, to emotional connections that are defined as either amorous or non-amorous. The numerical value is equivalent to the degree of emotion, with -3 being intense hate and +3 being intense love. The program also understands story tension, such as linking the word "wounded" with tension. This too is assigned a numerical value. Once these clusters of emotional links and tensions are established, the program begins what is called an "engagement reflection cycle". Basically this involves searching a database of story actions and other happenings, which are called "atoms", and determines the best match for the characters and contexts for that moment. The process repeats itself again and again until the system can no longer make any matches. At this point, the computer analyzes the story for coherence and "interestingness". The program views a story as interesting when tension levels increase and fall throughout the piece. If the program finds that the story is boring or incoherent in places, it will replace or insert atoms until a version is thought to be satisfactory. Question: How does the computer system describe the characters in its story? - Characters in the story are given different numerical values. - Characters are developed according to the tension preset. - Characters are designed by using the language MEXICA can understand. - Each character is valued for its value in the construction of the story.
Characters in the story are given different numerical values.

It may be one that allows you to express your personality while doing something you love and getting paid for it.
