Input: Consider Input: 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

Output: A

Input: Consider Input: Article: Wal-Mart is not just the world's largest retailer . It's the world's largest company, which sells in three months what number-two retailer Home Depot sells in a year. Wal-Mart exercises its power for just one purpose: to bring the lowest possible prices to its customers. At Wal-Mart, that goal is never reached. The retailer has a clear policy for suppliers: On basic products that don't change, the price Wal-Mart will pay, and will charge shoppers, must drop year after year. But what almost no one outside the world of Wal-Mart and none of its 21,000 suppliers know is the high cost of those low prices. To survive in the face of its pricing demands, makers of everything from bikes to jeans have had to close US plants in favor of obtaining products from abroad. Indeed, the real story of Wal-Mart, the story that never gets told, is the story of the pressure the biggest retailer constantly applies to its suppliers in the name of bringing us "every day low prices". The giant retailer' s low prices often come with a high cost. Wal-Mart' s pressure can crush the companies it does business with and force them to send jobs overseas. Are we shopping our way straight to the unemployment line? Of course, US companies have been moving jobs offshore for decades, long before Wal-Mart was a retailing power. But there is no question that the chain is helping accelerate the loss of American jobs to low-wage countries such as Thailand. People ask, "How can it be bad for things to come into the US cheaply?" Sure, it's great to have bargains. But you can' t buy anything if you' re not employed. There is no question that Wal-Mart's drive to squeeze out cost has benefited consumers. By now, it is accepted wisdom that Wal-Mart makes the companies it does business with more efficient and focused. Wal-Mart itself is known for continuous improvement in its ability to handle, move, and track goods. It is legendary for forcing its suppliers to redesign everything from their packaging to their computer systems. It is also legendary for quite straightforwardly telling them what it will pay for their goods.
Question: How do suppliers meet the requirements of Wal-Mart?
Options: (A) To sell even more goods in three months. (B) To cut down the employment rate sharply. (C) To charge shoppers at a much higher price. (D) To run the business in a well-organized way.

Output: D

Input: Consider Input: Article: Have you ever found yourself in this situation: You hear a song you used to sing when you were a child - a bit of nostalgia or "blast from the past," as we say. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago. Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages. Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of "listen-and-repeat" learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words. All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered. Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them. Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained in a catchy 3, or memorable 4, tune 5. Dr. Ludke said the findings could help those who struggle to learn foreign languages. On the University of Edinburgh's website Dr. Ludke writes, "This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area."
Question: According to the passage which language doesn't share the same root with Germanic or Romance languages?
Options: (A) Hungarian (B) Spanish (C) Italian (D) English
Output: A
