[EX Q]: Article: The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition . A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school. More must be done to fight the childhood obesity epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program--through snack bars and vending machines--has pretty much canceled out the benefits of all those efforts. Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium snacks elsewhere in school. Many states' school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses. Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students' health to buy office supplies. Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.
Answer: high calorie snacks
[EX A]: According to this passage, _ are to blame for the childhood obesity.

[EX Q]: Article: Some English words are made up of the same part and have different beginnings and different endings, such as import, export, report and transport. All these words, you can see, have the same "port", which comes from the Latin word, meaning "to carry" or "to move" from one place to another. And according to the bit at the beginning, which we call the prefix, the meaning changes. "Import" means "to carry in" or "to bring into a country"; "export", "ex" means "out of", so this word means "to carry out of the country"; "re" means "back", so the "report" means "to tell somebody, to bring back information to somebody"; "transport", "trans" means "across" and it means "to carry across one place to another". Let's look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus a suffix, thus meaning a person who does this thing. So "supporter" means somebody who supports. A "reporter" is somebody who reports. "Importer" is somebody who imports and "exporter" is somebody who exports, and so on.
Answer: a different meaning
[EX A]: By adding a prefix or a suffix to a root, we can get a word which has _ .

[EX Q]: Article: Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous. To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, Breaststroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training. In swimming there are certain rules every swimmer should follow: 1). Never swim alone! No matter how good you are in the water, don't risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble. 2). Don't go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach, Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive. 3). Don't smoke. Swimming depends on a healthy body; good lungs are part of it. 4). Work at any activity that builds muscles.
