Input: Joe's parents are farmers and they have a huge farm with cows, chickens, and ducks. Joe loves the farm and all the things he gets to play around and play on. One day, Joe's father told him not to get near a tractor that was sitting in the field. His father was worried that Joe would climb on it and hurt himself. Joe went out to the field and was feeding the horses and cows. When he was done, he saw the tractor his father told him not to get near. He knew that climbing on the tractor wouldn't hurt anything, so he did. He climbed on to the seat and sat there. Then, he pretended he was his father and pretended that he was driving the tractor. Joe's father saw him playing on the tractor and called for him. Joe heard his father calling for him and got off the tractor really fast. When he did that, he fell off and hurt his arm. Joe was in pain and his father came running to check on him and picked him up and sat him on a bench and asked him why he did that. Joe looked at his father and said, "I wanted to be like you." Joe's father gave him a hug and asked him if he wanted to ride with him on the tractor. Joe did and after he got a bandage on his arm, he and his father rode in the field on the tractor.

Does the response "Joe's mother" correctly answer the question "Who pretended to be driving the tractor?"?

Input: What if two children push a swing at the same time? Would the swing go higher? Yes, together their force would be more. It is common for forces to be combined. Most objects on Earth have at least two forces acting on them. Do you know what one of them is? Of course, that force is gravity. How many forces do you have on you right now? Gravity pulls you down toward the center of Earth. Your legs exert a downward force. They hold you up against the pull of gravity. Consider the example in Figure 1.3. A book is resting on a table. Gravity pulls the book downward. It has a force of 20 newtons. At the same time, the table pushes the book upward. Its force is also 20 newtons. The table opposes the pull of gravity.

Does the response "Slightly above than 20 newtons" correctly answer the question "At what level of force does the table oppose gravity?"?

Input: Washington The Iraqi government has agreed to let U.S. Rep. Tony Hall visit the country next week to assess a humanitarian crisis that has festered since the Gulf War of 1990, Hall's office said Monday. The Dayton Democrat, who has traveled to other crisis points including Sierra Leone and North Korea, will spend three days visiting hospitals and other facilities to seek understanding why aid has been ineffective in stemming malnourishment and other medical problems. Iraq has been under economic sanctions since the war ended, which some say have thwarted the country's ability to recover from the devastation of the bombing campaign. The Persian Gulf War destroyed much of the country's medical infrastructure, according to a report by the World Health Organization. In 1996 the WHO found that much of the population existed in a state of ''semi-starvation.'' Hall will be only the second member of Congress to travel in Iraq since the war, according to Hall's office. The last visitor was then-U.S. Rep. Bill Richardson of New Mexico, who went to help a pair of U.S. oilmen in diplomatic trouble. Hall flies to Amman, Jordan, on Friday, where he'll spend the night before driving to Iraq. Flights are not permitted into Iraq. Hall is to return to Washington on April 22. Story Filed By Cox Newspapers

Input: Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing populationmany of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los AngelesSalt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night).

Does the response "Las Vegas" correctly answer the question "What town had telephones, round-the-clock electricity, and a growing population by 1915?"?
