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: It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.
Question: According to the passage, which of the following is TRUE?
Options: (A) Freedman and his colleagues hired 400,000 Americans to collect date. (B) People who took part in Freedman's research are about 50 to 70 years old. (C) About 400, 000 Americans worked for Freedman's team for 13 years. (D) People who are 50 to 70 years old seldom drink wffee.

Answer: B
