Take a look at this train in Figure 1.11. It looks very futuristic. What do you notice about it? Did you notice that the train has no wheels? How can a train have no wheels? It doesn't need wheels. It actually floats, or levitates, just above the track. Magnets enable the train to do this. This is not a normal train. This is a maglev train. The word maglev stands for magnetic levitation. Because it has no wheels, there is no friction. Some magnets hold the train up. Other magnets are used to move the train forward. This train can go very fast. It can reach speeds up to 480 kilometers (300 miles) per hour! Magnets are pretty cool. What exactly is a magnet? How is it able to exert such force?

Animated history of the US. Of course the cartoon is highly oversimplified, and most critics consider it one of the weakest parts of the film. But it makes a valid claim which you ignore entirely: That the strategy to promote "gun rights" for white people and to outlaw gun possession by black people was a way to uphold racism without letting an openly terrorist organization like the KKK flourish. Did the 19th century NRA in the southern states promote gun rights for black people? I highly doubt it. But if they didn't, one of their functions was to continue the racism of the KKK. This is the key message of this part of the animation, which is again being ignored by its critics. Buell shooting in Flint. You write: "Fact: The little boy was the class thug, already suspended from school for stabbing another kid with a pencil, and had fought with Kayla the day before". This characterization of a six-year-old as a pencil-stabbing thug is exactly the kind of hysteria that Moore's film warns against. It is the typical right-wing reaction which looks for simple answers that do not contradict the Republican mindset. The kid was a little bastard, and the parents were involved in drugs -- case closed. But why do people deal with drugs? Because it's so much fun to do so? It is by now well documented that the CIA tolerated crack sales in US cities to fund the operation of South American "contras" It is equally well known that the so-called "war on drugs" begun under the Nixon administration is a failure which has cost hundreds of billions and made America the world leader in prison population (both in relative and absolute numbers).

Question: "What US president is indirectly linked by the author to the Buell school shooter?"

Response: "Carter"

Problem: Coleco Industries Inc., a once high-flying toy maker whose stock peaked at $65 a share in the early 1980s, filed a Chapter 11 reorganization plan that provides just 1.125 cents a share for common stockholders. Under the plan, unsecured creditors, who are owed about $430 million, would receive about $92 million, or 21 cents for each dollar they are owed. In addition, they will receive stock in the reorganized company, which will be named Ranger Industries Inc. After these payments, about $225,000 will be available for the 20 million common shares outstanding. The Avon, Conn., company's stock hit a high in 1983 after it unveiled its Adam home computer, but the product was plagued with glitches and the company's fortunes plunged. But Coleco bounced back with the introduction of the Cabbage Patch dolls, whose sales hit $600 million in 1985. But as the craze died, Coleco failed to come up with another winner and filed for bankruptcy-law protection in July 1988. The plan was filed jointly with unsecured creditors in federal bankruptcy court in New York and must be approved by the court.

Question: "What will unsecured creditors receive as a result of Coleco's Chapter 11 reorganization plan?"

Answer: "21 cents for every dollar"

Question:
(CNN) -- As Iranian President Mahmoud Ahmadinejad visited the U.N. General Assembly in New York last month, the spotlight was once again on Iran. And true to form, the Iranian president made his fair share of provocative statements for the Western media. But while Ahmadinejad's mercurial rants captured our media's attention, back in Iran a coordinated strategy against the women's movement continued. On the eve of Ahmadinejad's arrival to New York, Shiva Nazar Ahari, a prominent young female defender of human rights, received a heavy sentence of six years in prison on charges including the vague crime of "waging war against God" -- a convenient catch-all offense for anyone who criticizes the regime and its human rights record. There's no denying it -- Iran's women have had a bad year. Nazar Ahari joins a steadily increasing number of other women's rights activists who are in prison for no greater crime than their attempt to fight for the rights of the women. Hengameh Shahidi, Alieh Eghdam Doust, Bahareh Hedayat and Mahdiyeh Golrou have all been sent to Tehran's notorious Evin Prison on trumped-up charges related to their activism. And while Nobel Peace Prize laureate Shirin Ebadi, arguably the most internationally recognized Iranian women's rights activist, remains unable to safely return to her country, the government is targeting those affiliated with her for arrest and imprisonment, including her lawyer Nasrin Sotoudeh and her former aide Jinous Sobhani. Since the 2009 disputed elections and associated government crackdown on the overall reform movement, the government has increasingly targeted women activists. The reasons behind this go well beyond the misogynist nature of Iran's religious leadership. Rather, it is more part of a deliberate and calculated strategy of the Iranian authorities to strike at the heart of the regime's greatest vulnerability -- internal legitimacy with its own people. See more CNN.com opinion articles Iran's government recognizes and fears the broader power of the women activists who have been on the front line of reform in Iran for more than a decade. One can roughly draw an analogy between the women's movement in Iran to movements of religious groups in Burma or Tibet, or the labor "solidarity" movements in the former Eastern bloc and associated labor-Roman Catholic solidarity in Poland -- all advocating initially for the freedoms of a specific group but which provoked government fears for their transformative power to promote broader human rights progress. While the outside world occasionally reacts to the most egregious manifestations of Iran's repression of women -- such as the international condemnation associated with Sakineh Mohammadi Ashtiani, an Iranian widow sentenced to stoning on charges of alleged adultery -- these events are often portrayed simply as a consequence of the regime's archaic viewpoint about gender. After reading the above, is "Mahmoud Ahmadinejad" the correct answer to the question "Who came to New York the evening Nazar Ahari was sentenced?"? OPTIONS:
- no
- yes

Answer:
yes

Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.

Question: "If two items build unbalanced charges, the difference is called what?"

OPTIONS:
- no
- yes

Answer: ""Static electricity""

Response:
yes
