  2. Nov. 11, 2013 Did you ever wonder how ants find their way back to their nests, over vast distances? Some varieties of ants do it by smell; as they travel form the nest they deposit traces of scent. Other ants rely on astonishingly complex methods. Harvester ants are able to remember an incredible number of landmark objects along their trail. Myrmica ants and others use the sun as their point of reference. Amazingly, many ants apparently allow for the rotation of the earth as it changes the sun’s position overhead. The paragraph tells mainly-A. How ants deposit traces of scent.B. How ants locate homeward paths.C. How ants allow for the earth’s rotation.D. How ants remember landmark objects.

  4. Nov. 12, 2013 What a remarkable creature is the electric eel! This snakelike fish can produce an electrical charge that lasts only two thousandths of a second, but it can send out more than four hundred of these per second, totaling six hundred volts. A car battery gives only twelve volts! Even if the electric eel produced this amount of electricity for twenty minutes continuously, all it would need would be a rest of five minutes to “recharge its batteries.” It’s a shame that someone can’t harness its power. Can’t you just hear the service station attendant ask, “Want your oil and eel checked?” The paragraph tells mainly-A. Why the eel’s power has never been harnessed.B. What voltage of a car battery is.C. How long the electric eel’s charge lasts.D. Why the electric eel is a remarkable creature.

  6. Nov. 13, 2013 You may be surprised to know that hay fever doesn’t give you a fever, and that it has nothing to do with hay. It’s just a popular name for what doctors call an allergy to the pollen of certain plants. When you breathe this pollen in with the air, your eyes water and itch, your nose runs, and you sneeze. Some people don’t have the problem, and those who do are often born with it. The best-known hay fever in most parts of America is the one caused by ragweed, a green plant that grows in fields. Some people take pills or shots to help. Others just keep a good supply of handkerchiefs handy! The paragraph mainly tells- How hay fever is treated. What hay fever really is. Why hay fever victims sneeze. When hay fever usually strikes.

  8. Nov. 14, 2013 What tree can produce two hundred pounds of fruit in a single year, yet continue producing for 190 years? It is the stately date palm. Were it not for this single tree, some arid parts of the earth would be uninhabitable. One of the world’s most nutritious foods, thick sweet dates are a staple of diets in northern Africa and western Asia. Food is not the only product of this valuable tree. Its parts furnish building materials, fuel, matting, and rope; a liquor called arrack is made from the dates themselves; the buds are eaten as a vegetable; and even the ground-up seeds are fed to livestock. The paragraph mainly tells: How long the date palm lives. How useful the date palm is. How sweet and thick dates are. How arrack is made.

  10. Nov. 15, 2013 The green plant is the greatest producer of food on Earth, more powerful than the largest agribusiness corporation. Plants use chlorophyll, the substance that makes them green, to capture light energy from the sun. Then they add carbon dioxide from the atmosphere to make food sugars to feed themselves. Finally, they become either all or part of the food eaten by all the animals on Earth. The paragraph mainly tells: Why chlorophyll makes plants green. How carbon dioxide gets into the atmosphere. C. How plants produce food. D. How animals find plants to eat.

  12. Nov. 18, 2013There are many people walking around today with what looks like a cigarette pack under the skin of their chests. Actually, this tiny lifesaver is a pacemaker, placed there by a surgeon. The small machine delivers electrical impulses to the heart muscle at the right times. It is battery operated, with the battery usually located in the armpit. Without the pacemakers, the many patients who are using them might have insufficient blood supplied to their brains. As small as the apparatus is, it is sophisticated enough to have a feedback mechanism so that impulses are sent to the heart only when needed.The paragraph tells mainly—A. What people walk around withB. What the pacemaker doesC. How small the pacemaker isD. Where the pacemaker is located

  14. Nov. 19, 2013Miners needed to get rid of their gold as quickly as they got it out of the ground. During the California gold rush days, miners were being murdered at a rate of more than one a day. Any miner with gold was in danger of death and would have been happy to have his gold safeguarded and delivered to San Francisco or back home. Out of this need was born the Wells Fargo Company. Wells Fargo stagecoach carried the miners’ gold through bandit-filled mountains to the safety of a city bank. Wells Fargo became the name of a firm that miners could trust. The paragraph tells mainly – A. How many miners were murdered in a day B. Where Wells Fargo carried the gold C. Why city banks were safe D. How the Wells Fargo Company came into being
