In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Also on Feb. 12, a week before the ice dancing finals, Tokhtakhounov told Anissina's mother in a telephone call that the Russian federation official "had called me from America" to assure that "we are going to make" Anissina "an Olympic champion." He told her that the Russian skating federation official "will help -- he has two or three judges." On or about March 7, in a conversation between Tokhtakhounov and Anissina, she said she would have won the event without his assistance because the Russian judge did not vote for her and her partner. She also apologized for not calling to thank him earlier, but that Gailhaguet had forbidden her. She told Tokhtakhounov that she knew the FBI had interviewed Gailhaguet because of information that Tokhtakhounov "was involved with the results" of the ice dancing. He assured her that it was nonsense, but that Gailhaguet "knows my name very well -- he tried to help me, and later he made stuff up to scare you so you would not connect me to him even more." The conversations seem to indicate a familiarity between Tokhtakhounov and Anissina. Tass, the official Russian news agency, reported that Anissina attended a ceremony in 1999 at a Paris hotel honoring Tokhtakhounov for his philanthropy. That Russian organized crime may have infiltrated international sport at the Olympics stunned Phyllis Howard, president of the U.S. Figure Skating Association. "This is a criminal act and it certainly puts things in a different league," Howard said. Lloyd Ward, chief executive officer of the U.S. Olympic Committee, said in a statement, "Competitors from all nations must be assured that they compete on a level playing field." <sep>Who is going to help making Anissina "an Olympic champion"?<sep>Tokhtakhounov
Yes

The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis. <sep>Some of the Sun's energy travels to Earth and becomes energy for what process?<sep>Energy used for photosynthesis
Yes

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. <sep>Why do your hands become warmer when you rub them together?<sep>From chemical reaction
No
