Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Question: "The force that holds our moon in place, is an example of what type of force?"

OPTIONS:
- no
- yes

Answer: "A type of non-contact force, not example"

Response: yes

The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis.

Question: "What do scientists think to be the immediate cause of how Earth's magnetic field is generated? Choose the relevant options"

Response: "They discovered that Earth has an inner and outer core"
OPTIONS:
- no
- yes

Problem: I wondered if that were my case--if I rode out for honour, and not for the pure pleasure of the riding. And I marvelled more to see the two of us, both lovers of one lady and eager rivals, burying for the nonce our feuds, and with the same hope serving the same cause. We slept the night at Aird's store, and early the next morning found Ringan. A new Ringan indeed, as unlike the buccaneer I knew as he was unlike the Quaker. He was now the gentleman of Breadalbane, dressed for the part with all the care of an exquisite. He rode a noble roan, in his Spanish belt were stuck silver-hafted pistols, and a long sword swung at his side. When I presented Grey to him, he became at once the cavalier, as precise in his speech and polite in his deportment as any Whitehall courtier. They talked high and disposedly of genteel matters, and you would have thought that that red-haired pirate had lived his life among proud lords and high-heeled ladies. That is ever the way of the Highlander. He alters like a clear pool to every mood of the sky, so that the shallow observer might forget how deep the waters are.

Question: "What is the name of the narrator's rival in love?"

Answer: "Ringan"

OPTIONS:
- no
- yes
Answer: yes

Question:
Roberta Adams skipped the thick how-to guide on child-custody forms and sat down at a computer at the Lamoreaux Justice Center in Orange on Wednesday. The Garden Grove woman answered a series of questions to create and print a form to file with the court. "It's easy," said Adams, 25. "I thought I'd have all kinds of questions and have to take the forms home." A University of California, Irvine, study released Wednesday found an interactive computer system effectively helps people fill out paperwork for restraining orders, eviction defense, small-claims cases and requests for filing-fee waivers. Not only does the system make life easier for people who can't afford a lawyer, but it also might improve efficiency in the courts because the forms, which are printed out when completed, are easy to read and are being filled out correctly, the study found. Since the program started in 2000, more than 6,000 people have used the free system, located in public buildings throughout Orange County. The system was developed by the Legal Aid Society of Orange County with about $800,000 in grants. The program avoids legal jargon, offers a courthouse video tour and sticks to a fifth-grade vocabulary. Users can choose English, Spanish or Vietnamese. Kiosks are in courthouses in Fullerton and Orange, the district attorney's family-support office, the Legal Aid Society in Santa Ana, Irvine City Hall and the San Juan Capistrano Library. The program is also available online. Bob Cohen, executive director of Legal Aid, said the study should clear the way for expansion throughout California. Locally, a program for divorce petitions will be added this summer. Cohen said the system proves the benefit of technology tailored to those who aren't computer-savvy. He said much of the technology now available requires Internet skills and access. Low-income people, however, have less access to computers and less experience using them. "Our clients have to catch up, and they have to become a part of the mainstream," Cohen said. After reading the above, is "The program was developed by the Legal Aid Society of Orange County with about $800,000 in grants" the correct answer to the question "How did the program come about?"? OPTIONS:
- no
- yes

Answer:
yes

Temperate climates have moderate temperatures. These climates vary in how much rain they get and when the rain falls. You can see different types of temperate climates in Figure 2.40. Mediterranean climates are found on the western coasts of continents. The coast of California has a Mediterranean climate. Temperatures are mild and rainfall is moderate. Most of the rain falls in the winter, and summers are dry. To make it through the dry summers, short woody plants are common. Marine west coast climates are also found on the western coasts of continents. The coast of Washington State has this type of climate. Temperatures are mild and theres plenty of rainfall all year round. Dense fir forests grow in this climate. Humid subtropical climates are found on the eastern sides of continents. The southeastern U.S. has this type of climate. Summers are hot and humid, but winters are chilly. There is moderate rainfall throughout the year. Pine and oak forests grow in this climate.

Question: "What are characteristics of a Mediterranean Climate:?"

OPTIONS:
- no
- yes

Answer: "Temperatures are mild, rainfalls are moderate, rain falls mostly in the winters and summers are dry"

Response:
yes
