Example Input: Article: Mark Twain was a famous American writer in his day. He liked to play jokes on his friends. One day one of his friends lost his wallet and asked Mark Twain to pay his train ticket for him. "But I don't have enough money to pay both your ticket and mine," Mark Twain said. The friend didn't know what to do. "We can do this," said Mark Twain." We can get on the train and when the conductor came to check the tickets , you can hide under my seat." Later, however, when the conductor came to check the tickets, Mark Twain gave him two tickets --- one for himself and one for his friend . Then he explained in aloud voice," My friend is a strange man. When he travels on a train, he does not like to sit on the seat." Of course everyone in the train looked at the poor friend under the seat and laughed at him loudly.

Example Output: Why did the friend ask Mark Twain to pay his train ticket for him?

Example Input: Article: Mail was usually carried west on ships that sailed around the bottom of South America and then north to California.That could take several months. So, in eighteen fifty-seven, D.C.Lawmakers in Congress in Washington wanted to make it possible to send mail all the way across the United States by land.Congress offered to help any company that would try to deliver mail overland to the West Coast. A man named John Butterfield accepted this offer. He developed plans for a company that would carry the mail--and passengers, too. Congress gave John Butterfield six hundred thousand dollars to start his company. In return, he had to promise that the mail would travel from Saint Louis, Missouri, to San Francisco, California, in twenty-five days or less. It was not possible to travel straight through because of the Rocky Mountains and the deep snow that fell in winter. So the stagecoach would travel south from Saint Louis to El Paso, Texas, then over to southern California, then north to San Francisco. The distance was about four thousand five hundred kilometers. Two hundred of these stations were built, each about thirty-two kilometers apart. The workers were to quickly change the horses or mules whenever a stagecoach reached the station. There could be no delay. Each stagecoach was to travel nearly two hundred kilometers a day. One hundred stagecoaches were built and painted red or dark green. They were the most modern coaches that money could buy. They were designed to hold as many as nine passengers and twelve thousand pieces of mail. The seats inside could be folded down to make beds. Passengers either slept on them or on the bags of mail. The cost would be one hundred fifty dollars to travel from Saint Louis to San Francisco. If a passenger was not going all the way, the cost was about ten cents a kilometer. The passengers had to buy their own food at the stations. The stagecoach would stop for forty minutes, two times a day. The company warned passengers about the possible dangers. A poster said: "You will be traveling through Indian country and the safety of your person cannot by granted by anyone but God."
Answer: The history of the first stagecoaches carrying mail to the American West.
Example Output: What is the passage mainly about?

Example Input: Article: "Tear them apart!" "Kill the fool!" "Murder the referee !" These are common remarks one may hear at various sporting events. At the time they are made,they may seem innocent(,) enough. But let's not kid ourselves.They have been known to influence behavior in such a way as to lead to real violence. Books have been written about the way words affect us. It has been shown that words having certain meanings may cause us to react in ways quite foreign to what we consider to be our usual behavior. I see the term "opponent" as one of those words. Perhaps the time has come to delete it from sports terms. The dictionary meaning of the term "opponent" is "enemy", or "one who opposes your interests." Thus, when a player meets an opponent, he or she may tend to treat that opponent as an enemy. I remember an incident in a handball game when a referee refused a player's request for a time out for a glove change because he did not consider them wet enough. The player went away to rub his gloves across his wet T-shirt and then screamed, "Are they wet enough now?" In the heat of battle, players have been observed to throw themselves across the court without considering the effect that such a move might have on anyone in their way. I have also witnessed a player reacting to his opponent's intentional and illegal blocking by hitting him with the ball as hard as he could during the course of play. Off the court, they are good friends. Does that make any sense? It certainly gives proof of a court attitude which differs from normal behavior. Therefore, I believe it is time we elevated the game to the level where it belongs, setting an example to the rest of the sporting world. Replacing the term "opponent" with "associate" could be a good way to start. The dictionary meaning of the term "associate" is "friend" or "companion." You may soon see and possibly feel the difference in your reaction to the term "associate" rather than "opponent".
Answer: He wet his gloves by rubbing them across his T-shirt.
Example Output:
What did the handball player do when he was not allowed to change his gloves?
