Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.
"Why do your hands become warmer when you rub them together?" is "From mechanical reaction"?

Input: You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air.

Does the response "When blood vessels dilate, or widen" correctly answer the question "What increases blood flow to the body's surface?"?

OPTIONS:
- no

Before the mysterious disappearance of one of its passenger jets this month, Malaysia wasn't a country used to finding itself dominating headlines around the world. Some of its Southeast Asian neighbors, including Indonesia and the Philippines, have suffered devastating natural disasters in recent years and are all too familiar with the media frenzy that accompanies a major crisis. But Malaysia has largely managed to stay out of the international spotlight since its independence from British colonial rule more than half a century ago. "It is one of these countries, because of its geography, that doesn't have earthquakes," said Ernest Bower, senior adviser for Southeast Asia studies at the Center for Strategic and International Studies. "It doesn't have tsunamis. It hasn't been tested with a disaster like this." The disappearance of Malaysia Airlines Flight 370 has thrust the government into the dazzling glare of worldwide attention. And it hasn't emerged with very good grades. "I think on a stress test, they're failing," Bower told CNN's Jake Tapper, pointing to the government's coordination of different agencies and communication with other countries. China among critics Criticism and complaints have come from other countries involved in the search for the missing plane, including China and Vietnam, and from the relatives of passengers. Malaysian officials have created confusion by issuing contradictory statements on key aspects of the investigation. The majority of the people on board the plane were Chinese, and Beijing has increasingly voiced its displeasure with the search, especially after Malaysia announced over the weekend that evidence suggested the plane had been deliberately flown west into the Indian Ocean, away from its last confirmed location over the South China Sea. "The new information means the intensive search in the South China Sea for the whole past week was worthless and would never bear fruit," said a commentary published by China's state-run news agency Xinhua. "Even worse, the golden time for saving possible survivors, if any, was generously wasted."

Question: "Why might Malaysia not suffer the kinds of natural disasters experienced in Indonesia and the Philippines?"

OPTIONS:
- no
- yes

Answer: "Because it is not by the ocean"

Response: no

Unfortunately, because the zooming is rather fast, it is easy to miss the rest of the sentence, so as you correctly note, some viewers got an incorrect impression. It would have been fair for Moore to point out this possible misinterpretation on his website. However, the claim of deliberate distortion is ludicrous for several reasons: a) Moore clearly states that "before he came to Flint", Heston gave an interview. In the excerpt from said interview, we can see that it is from March. If Moore wanted to deceive his viewers, why would he say this, and show the month the interview was published? b) Why should Moore leave the words "Clinton is on the Today Show" visible in the text, which is necessary to correctly interpret the highlighted part? I reviewed the sequence several times and it is perfectly possible to see this text without pausing. c) Both the "soccer mom" interview and the sequences showing the NRA rally make no effort to distort the fact that this rally happened months after the fact. The camera lingers on Bush/Cheney posters, and the protestor is quoted as saying that "we wanted to let the NRA know that we haven't forgotten about Kayla Rolland". You make the hysterical claim that the interview "may be faked" (on the basis that no name is shown for the interviewee), but if Moore had faked it, why the hell should he put this sentence in the protestor's mouth, which directly contradicts the conclusion that the rally happened hours after Kayla's death? Why did Moore, the masterful deveiver, not edit this sequence out? This makes no sense. Opinions may vary on how tasteless it was for Heston to hold a pro gun rally on the location of the nation's youngest school shooting months after the fact, but this sequence of "Bowling" is without doubt the most unfair to Heston. The claims of deliberate distortion don't hold up when viewing the whole scene, though -- as "Hanlon's Razor" states, one should never attribute to malice what can be attributed to incompetence. The somewhat inept editing of the NRA press release has led some viewers to wrong conclusions, which is unfortunate, but Moore's critics have no interest in viewing the matter fairly. Had they done so, Moore himself would probably have apologized for the gaffe. In any case, at no point does Moore make a false statement, in contradiction to claims by critics that his documentary is "full of lies".

Question: "When did Heston give an interview?"

Response: "Right after March ended"

Problem: We were cornered in a sort of way already. But these butchers up the cavern had been surprised, they were probably scared, and they had no special weapons, only those little hatchets of theirs. And that way lay escape. Their sturdy little forms--ever so much shorter and thicker than the mooncalf herds--were scattered up the slope in a way that was eloquent of indecision. I had the moral advantage of a mad bull in a street. But for all that, there seemed a tremendous crowd of them. Very probably there was. Those Selenites down the cleft had certainly some infernally long spears. It might be they had other surprises for us.... But, confound it! if we charged up the cave we should let them up behind us, and if we didn't those little brutes up the cave would probably get reinforced. Heaven alone knew what tremendous engines of warfare--guns, bombs, terrestrial torpedoes--this unknown world below our feet, this vaster world of which we had only pricked the outer cuticle, might not presently send up to our destruction. It became clear the only thing to do was to charge! It became clearer as the legs of a number of fresh Selenites appeared running down the cavern towards us.

Question: "Who were shorter and thicker than the mooncalf herds?"

Answer: "Bulls"
