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: Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning off the rights to name the 4-inch "owl eye" butterfly, which lives in Sonora, a Mexican state bordering Arizona. "That would support at least two years of research for our team down in Mexico," Warren said. "Money goes a long way down here in Mexico." According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money. Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million. The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico. The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a "new" model of butterfly. After checking photos and comparing it with other known species, they determined it was a separate species.
Answer: Near the US-Mexico border.
Example Output: Where did the researchers discover the new species of butterflies?

Example Input: Article: I have always known my kids use digital communications equipment a lot. But my cellphone bill last month really grabbed my attention. My son had come up to nearly 2,000 incoming text messages, and had sent nearly as many. Of course, he was out of school for the summer and communicating more with friends from a distance. Nevertheless, he found time to keep a summer job and complete a college course in between all that typing with thumb. I was even more surprised to learn that my son is normal. "Teenagers with cellphones each send and receive 2,272 text messages a month on average, " Nielsen Mobile said. Some experts regret that all that keyboard jabber is making our kids stupid, unable to read non-verbal cues such as facial expressions, gestures, posture and other silent signals of mood and attitude. Unlike phones, text messaging doesn't even allow transmission of tone of voice or pauses, says Mark Bauerlein, author called The Dumbest Generation: How the Digital Age Stupefies Young Americans and Jeopardizes Our Future. Beyond that, though, I'm not sure I see as much harm as critics of this trend. I' ve posted before on how I initially tried to control my kids' texting. But over time, I have seen my son suffer no apparent ill effects, and he gains a big benefit, continuing contact with others. I don't think texting make kids stupid. It may make them annoying, when they try to text and talk to you at the same time. And it may make them _ when buzzing text message interrupt efforts to noodle out a math problem or finish reading for school. But I don't see texting harming teens' ability to communicate. My son is as accustomed to nonverbal cues as any older members of our family. I have found him more engaged and easier to communicate with from a great distance. because he is constantly available by means of text message and responds with faithfulness and speed.
Answer: It will cause damage to the development of teens' intelligence.
Example Output:
What is Mark Bauerlein ' s attitude to texting?
