Question: 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.
Question: An elephant usually travels at a speed of _ per hour.
Options: (A) around 6 miles (B) around 25 miles (C) no more than 6 miles (D) more than 25 miles

Answer: A

Question: Article: Heather Jack and her family, including her two children, usually spend the Christmas holidays preparing a feast--for others to eat. Last Christmas Eve, they went to a house in the neighborhood and prepared a dinner for an elderly woman and her son, who has muscular dystrophy . They stayed for an hour and chatted before heading home to prepare for a visit from Santa . "I think it is that kind of direct experience that many find so meaningful," says Heather, president and founder of The Volunteer Family, a Boston-based organization dedicated to matching families with volunteer opportunities, both during the holidays and year-round. "It's a great way for parents to involve the kids." In a holiday season that stretches from before Thanksgiving to just after the New Year, it's nice to hear stories about people with their children giving instead of receiving. Last December Gary and Debra Danoff and their two teenage sons drove to the Washington, D. C. Jewish Community Center(JCC) and spent Christmas morning in the Center's kitchen preparing a feast for homeless shelters. By choosing to prepare meals for the homeless, the Danoffs bring together a belief in community service with their love of cooking, "It feels good to prepare food with our kids for other people at Christmas," says Gary. "We want them to know that many people don't have the ability to go to the supermarket and pick the foods they want to eat and pay for them." The Danoffs were in good company. Across the city, at least 1000 volunteers with their children went across the region to provide food to the poor people as part of the D. C. JCC's annual "December 25th Day of Service", now in its 22nd year.

Question: Article: Humor is very important in any relationship. It is truly a unique gift when someone has the ability to make another laugh. Humor allows a person to forget his troubles and focus on positive aspects of his life. Personally speaking, making another laugh, whether it is a family member, a close friend, or even a stranger, has always given me a good feeling! Humor plays an important role in our family lives. The interaction , between husband and wife and between a parent and a child, is very important, just thinking how much better our relationships would be if we would take the time to laugh. Humor and laughter are especially important during difficult times. No matter how bad a person may feel, a family member or a friend can make him feel good by laughing with him. I once had a co-worker, for whom there was no humor in her daily life. She seldom smiled and seemed to focus on only the negative or the dark side. One day I was told she was very unhappy, had few friends, and had poor relations with family members. Later, I learnt that she couldn't remember laughing or enjoying life. In order to enjoy her life, she was advised to have humor and laughter each day of her life. In the end, it seemed to make a huge difference. We do live in a difficult world. "Stress" seems to be a major factor contributing to health problems of our society. So, in order to live easily, we should put humor into our daily lives. I have a plaque hanging on the wall, which reads "Live, Love and Laugh"!
