(CNN) -- English club Chelsea have completed the signing of Oriol Romeu from Spanish and European champions Barcelona. The 19-year-old is currently playing for Spain at the World Under-20 Championships in Colombia and has signed a four-year deal with last season's Premier League runners-up. The deal is worth $7 million and includes a buy back clause, set at $14 million after the first year and $21 million after the second. Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004. The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010. He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador. Chelsea official web site confirmed the signing and said Romeu is "renowned for his strength and his expansive passing ability." Another player leaving Barcelona is Jeffren Suarez after he agreed to join Sporting Lisbon. The Portuguese outfit have paid $5 million for the 23-year-old which, like the Romeu deal, includes a buy back option. Jeffren joined Barca from Tenerife in 2004 and made his debut for the Catalan club in the 2006-07 season.

Problem: Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

Question: "What happens to the size of the chest when the diaphragm muscle tightens?"

Answer: "Increases"

Question:
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". After reading the above, is "The text that was meant to explain the NRA rally" the correct answer to the question "What text gave viewers the wrong impression"? OPTIONS:
- no
- yes

Answer:
no

Input: Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects.

Does the response "A smooth surface" correctly answer the question "In order to slide across ice more easily, would you want something on your feet that had a smooth surface or a rough surface?"?
