If teens could reduce the salt they take in every day by 3,000 milligrams (mg), they would cut their risk of heart disease and stroke  greatly in adulthood, researchers say. Based on the results of a computer modeling analysis, researchers found that a 3,000 mg reduction in sodium  by teenagers could reduce hypertension by 30 percent to 43 percent when they become adults. Hypertension, or high blood pressure, is a common condition that may have no symptoms for years, but can eventually cause serious health conditions, including heart attack and stroke. Other benefits over time as teens hit 50 years of age include a 7-12 percent reduction in coronary heart disease , an 8-14 percent reduction in heart attacks, and a 5-8 percent reduction in stroke. Fast food typically contains too much sodium. One bag of Nacho Cheese Doritos has 310 milligrams. Pizza is one of the biggest problems for teens when it comes to sodium, according to data from the National Center for Health Statistics. "The additional benefit of lower salt intake early is that we can hopefully change the expectations of how food should taste, ideally to something slightly less salty," says Dr. Kirsten Bibbins-Domingo, the lead author of the study and associate professor of medicine at the University of California, San Francisco. "Most of the salt we eat is not from our salt shaker , but salt that is already added in food that we eat." she added. Which of the following can be the best title for the text? A) Teens Cutting Salt for Healthier Adulthood B) Diet and Health C) Sodium Brings Health Concerns D) A Cause of Hypertension

Treat with Respect The speed with which Man is changing the face of Earth has outstripped all the mighty processes of nature put together. In his haste to supply himself with increasing quantities of Earth's treasures he risks destroying one he greatly needs, his natural surroundings. Some countries set aside unspoiled areas of natural beauty. prefix = st1 /Canadahas the largest system of national parks in the world, 29 in all covering about 13 million hectares, preserving the different landscapes and the plant and animal life. Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australiadrifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits  are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills. However Man tries to look after Earth, the fact is that he is using up at a great rate resources, especially fuel resources, which have taken millions of years to accumulate and which he cannot renew. Yet every day the Earth receives a huge supply of energy from the Sun. Man has made several experiments in using solar energy to heat furnaces , cookers, and water-distillers. In space technology, e.g. on satellites, solar cells convert  sunlight into electricity. Houses and offices have been designed which are centrally heated by water or air heated by the sunlight. When Man can trap and store this energy, so that he can use it exactly as he needs it, he will have not only an endless supply, but a clean and safe one. According to this selected passage, which energy is considered to be endless, clean and safe? A) Energy from lake waters. B) Energy from fuel resources which have taken millions of years to accumulate. C) Energy from forests. D) Energy from the Sun.

Years ago there was a group of kids who would hang around at some local ponds  in the woods near their houses in Warwick, Rhode Island. In summer they caught frogs and fish. When winter arrived they couldn't wait to go skating. Time passed, and the ponds became the only open space for the kids to enjoy themselves in that neighborhood. One day a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called apartments. So the boy went door to door and gathered more than two hundred signatures to stop the development. A group of citizens met and decided to support him. At the meeting of the town planning organization,the boy was quite nervous at first and spoke very softly. But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds,his voice grew louder. He told the town officials that they should speak for the citizens. He also insisted that they should leave enough space for children. A few days later,the developer stopped his plan. Nine years later, when that teen was a senior in college, he was informed that the developer was back with his proposal to build apartments. Now twenty-two years old, he was studying wetlands ecology. He again appeared before the town planning organization. This time as an expert, he used environmental protection laws to explain _ on development in and around wetlands and the knowledge of wetlands ecology to help to improve the development. Finally some apartments were built, but less than half the number the developer wanted. The ponds where those kids used to hang around were protected by a piece of natural land, and are still there today. Which statement is true according to the passage? A) The apartments were built as the developer had planned. B) The grown-up boy helped to protect the wetlands as an expert. C) The developer stopped the boy's plan at the meeting years ago. D) The ponds were filled in and some apartments were built on them.
