Article: Tips for avoiding traffic jams The radio has more than just music. Check the local news station for the latest traffic report. Or go online and check traffic cameras before you set out. If there is a jam, you'll be prepared and can try another route. Take the road less traveled. Although highways may be the most direct route, back roads can be much less crowded, which can save you from the frustration of the stop-and-go traffic. Rush hour isn't just a lovely nickname. It means the morning and afternoon traffic lasts for several hours, but they are still called "rush hour" for a reason--everyone's on the road and in a hurry to get somewhere. Treat rush hour like bad weather--if you don't have to go anywhere, stay off the roads. Tips for those unavoidable traffic jams Don't break the law. You've gone 30 feet in 30 minutes and all of a sudden you see people using the shoulders . Don't behave like them. Not only is this illegal, but also there's a good chance they'll get caught or cause even more problems. Pay extra attention to zig-zaggers when some people are anxious, they may start changing lanes every 5 seconds or cut you off. Keep checking your windows and mirrors for these lane changers. Look for an escape. If it is possible to exit the road safely, do it. Use a GPS unit, and you can change your route mid-trip if needed. Be courteous. Good manners could help you avoid a possible accident. Allow people in from a lane that is ending. Speeding up to keep them out increases your chances of an accident.

Article: Wild elephants live in herds of 10 to about 50. The leader is usually a female. A herd can go through a forest quietly. It travels in a single line. It goes about 6 miles an hour. When frightened, it may run at about 25 miles an hour. When they reach water, elephants swim across. They are great swimmers. Elephants eat grass, leaves, small branches, and bark. They particularly like the tender leaves on the top of trees. How do they get these leaves? They use their heads to knock trees down. They can easily knock down a 30-foot tree. Elephants also eat berries, mangoes, coconuts, corn, and sugar cane. They love salt. A wild male adult eats 500 to 600 pounds of food a day. Many people want to find the graveyards of elephants. There is a strong belief that such graveyards exist. Here is why. Bones and tusks of dead elephants have almost never been found. Searches have been made in forests. Grassy plains have been searched too. But neither bones nor tusks are found. Elephants don't live forever. Where are their bones? They don't just bury themselves. Here is one belief. When an elephant gets sick or old, it instinctively knows death is near. It leaves the herd. It goes off to a secret graveyard. The place is known only to elephants, and perhaps other animals, but not to humans. Obviously, such a graveyard would be filled with tusks. These were once very valuable. The objective of explorers was to find this "gold" mine. This graveyard belief may be a truth or a myth. But it is romantic. It would be nice if it were true.

Options: (A) around 6 miles (B) around 25 miles (C) no more than 6 miles (D) more than 25 miles

Article: If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment. Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year. However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey. Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects! While it is true that some species of insects harm or annoy us, _ . You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings.
