Example Input: Context: In America, when the eighth graders leave the middle school, they are often worried about moving to the high school. It is a hard time for them, but it can be an exciting one as well. To make it easier, students need to get familiar with their school. Even though they've done this already in the middle school, it's still important to find where their classrooms are. Most schools take students to the high school for a visit at the end of their eighth grade year. And, most schools also have a freshman speech for parents and students before the first year begins. Sometimes the main office will give away a map of the school. This can help students and parents to find different places in the school. One way to know your high school more and make new friends is to join a club or play a sport. Schools often offer chances to join different clubs and sports. Fall activities begin in August before the first day of school. If you are not interested in sports, there are clubs for any interest, such as drama, dance, chess, photography, community service, etc. These clubs allow students from different grades. By joining an activity, students can find new friendships, not to mention improving their chances in future college applications . The school office will have a list of activities offered at the school and information on how to join them. What's more, to have a great start to a high school year, students can write down some of their worries, and ask for help from teachers and school workers. 
 Question: When do many schools take students to visit their new high school?
Example Output: at the end of their eighth grade year

Example Input: Context: Jack Elgin is the European editor of The Economist, which is based in London, England. Jack has a wife named Maria and three kids named Joanne, Julia, and Andrew. Jack subtly changes the family vacation from a lazy week of Mediterranean fun and sun in Corfu, Greece, to a tour of India, because of a story he has to cover. Maria is not as impressed by this as the kids are. Jack himself envisioned a chance to simultaneously work an easy reporting assignment and spend a little quality time with his family. But on the way to India, the airplane, a 747 owned by AM Air, an American airline, makes an unscheduled stopover in Limassol Cyprus, because of a mechanical problem. After a while of waiting inside the Limassol airport, everyone gets back on the plane -- which is then hijacked by a group of terrorists known as the August 15th Movement, led by a Serbian man named Ivanic Loyvek and his right-hand man Karadan Maldic. The terrorists take a silver briefcase from an diplomatic courier, an older man, and it appears to be an important object of their hijack. And they are demanding $50,000,000 from the US State Department in one hour, or everyone on the airplane will die.The demand is met, and Loyvek and Maldic start releasing the women and children, with the men to go last. But as soon as a front passenger door is opened, the local police begins shooting. Inside the plane, the owner of the briefcase retrieves it, only to be killed the terrorists, who take it again.The flight attendants frantically open the rest of the airplane's doors and start getting passengers out, but the terrorists start killing passengers, leading to an explosion. Maria, Joanne, and Julia get out of the airplane, and then Jack, holding Andrew, gets out -- only to watch Maria, Joanne, and Julia get shot by the terrorists. Jack tries to hide Andrew's face so he can't see. Maria and Joanne are killed, but Julia burns to death while crying for help.Jack and Andrew survive. 15 passengers die, and Loyvek and Maldic, the surviving terrorists, escape, knowing that they now have the $50,000,000. Back in London, a devastated Jack is told that the terrorists were captured, but they were released and deported secretly, with no charges and no arrest, the result of some awfully compromised politics. Jack is understandably enraged that Loyvek and Maldic got off scot-free. While helping Andrew cope, Jack tries all the legal ways to ensure justice for his family, but to no avail.Jack even pays a visit to Henry Davidson, a CIA agent who works at the American Embassy in London. Davidson tells Jack that there's little that can be done. The American and British governments are completely impotent when it comes to going after Loyvek and Maldic. Jack decides he has no choice in the matter but to seek revenge. With the help of his ex-intelligence operative friend Kate Stockton, who is well-schooled in the finer points of international intelligence, Jack becomes a one-man anti-terrorist squadron, searching for Loyvek and Maldich. He finds a warehouse they apparently are using as a headquarters. Breaking in, he finds some papers which he takes, and some weapons. The terrorists return, find a flashlight Jack was using, and begin searching the warehouse. Jack returns upstairs, retrieves a machine pistol and loads it with a magazine. He kills three terrorists before escaping.He later breaks into the home of a friend at MI6 and steals a Walther PPK pistol from his home. He shows up at a theatre and makes a scene at the bar, to be sure he is noticed by the bartender. He then follows one of the terrorists in his taxicab, killing him with that weapon. He returns to the theatre and makes a point of apologizing to the bartender. The next day he goes pheasant hunting with his MI6 contact in case he is tested for gunpowder residue.Dogging Jack's trail is FBI agent Jules Bernard, who's cooperating with Scotland Yard on anti-terrorist activities, and who suspects 
 Question: Who is Jack's wife?
Example Output: maria

Example Input: Context: A rock is a naturally formed, non-living Earth material. Rocks are made of collections of mineral grains that are held together in a firm, solid mass (Figure 1.1). How is a rock different from a mineral? Rocks are made of minerals. The mineral grains in a rock may be so tiny that you can only see them with a microscope, or they may be as big as your fingernail or even your finger (Figure Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals. Texture is a description of the size, shape, and arrangement of mineral grains. Are the two samples in Figure 1.3 the same rock type? Do they have the same minerals? The same texture? The different colors and textures seen in this rock are caused by the presence of different minerals. A pegmatite from South Dakota with crystals of lepidolite, tourmaline, and quartz (1 cm scale on the upper left). Sample 2 Crystals are tiny or microscopic Magma erupted and cooled quickly Andesite As seen in Table 1.1, these two rocks have the same chemical composition and contain mostly the same minerals, but they do not have the same texture. Sample 1 has visible mineral grains, but Sample 2 has very tiny or invisible grains. The two different textures indicate different histories. Sample 1 is a diorite, a rock that cooled slowly from magma (molten rock) underground. Sample 2 is an andesite, a rock that cooled rapidly from a very similar magma that erupted onto Earths surface. A few rocks are not made of minerals because the material they are made of does not fit the definition of a mineral. Coal, for example, is made of organic material, which is not a mineral. Can you think of other rocks that are not made of minerals? Click image to the left or use the URL below. URL: Click image to the left or use the URL below. URL:
