Question: Write a multi-choice question for the following article, with the given choices and answer: Article: My destination is the River Walk, one of the most popular places in all of Texas. In the first half of 20 century, to control flooding, the city fathers began redirecting the San Antonio River. They built a network of canals that pass through the downtown area. At nearly every street corner, stairs lead down to walkways on both sides of the canals. The River Walk is linked with cafes, bars, shops --- and, of course, plenty of bridges. You can easily cross over to the other side without having to return to the street. It's a constant party along the River Walk, with music and festivals throughout the year. The Mud Festival, for example, takes place each January, when the city empties this section of the river to clean it out. That's when the Mud King and Mud Queen are crowned. No visit to Texas would be complete without seeing a --- another aspect of this part of the country that is completely foreign to someone from New England. The announcer walks on stage and gets the crowd excited with talk about the courageous cowboys who'll be performing. While he's talking, a band plays sad songs about love gone wrong. Suddenly the announcer calls for silence. He takes off his tall hat and asks us to join him in prayer. We pray for the cowboys who are, we are told, risking their lives to entertain us, as well as for the bulls and other animals taking part in the shows. We pray for the tourists who are visiting. The rodeo gets going and the fun begins. Our prayers for the cowboys and animals are answered, and nobody gets hurt. But as we walk over to the cowboy dance hall after the show to enjoy a Texas-size barbecue, it's clear that not enough prayers were said for the bulls' less athletic relatives --- the ones not chosen for rodeo work. They'll be our meal. It seems that moving too slowly has its disadvantages, too. Options: A Mud Festival dates back to the first half of 20 B Mud Festival is held in January every year.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: New findings suggest that brainy card games such as contract bridge may temporarily raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune cells, according to the research reported last week. A researcher, Diamond, studied bridge players from a women's bridge club. She chose bridge players because the game includes skills stimulating a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system. The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland and used by the immune system against diseases. The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology , whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated systems. What isn't clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses. Options: A a brain B a white blood C a red blood D a kind of dangerous blood Answer: B a white blood Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple's case, developers can also obtain the location information for each photo. Senator Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday. "We asked them if they could find a way on their own to prevent Apple from having access to private information," Mr. Schumer said. "They were friendly and open to the idea that this ought to be changed." On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further. "It worries people to think that one's personal photos, address book, and who knows what else can be obtained and even posted online without permission," Mr. Schumer wrote in his letter to the F.T.C. "If the technology exists to open the door to this kind of privacy invasion , then surely technology exists to close it, and that's exactly what must happen." Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further. He said other companies had been willing to work with his office to fix issues. "I'm optimistic that we can get this changed without any regulation," he said. "If it's not changed, then we'll turn to the F.T.C., and if that doesn't work then we'llconsider legislative approach." The F.T.C. has warned companies to try to be more vigilant in their efforts to protect consumers when it comes to privacy. Options: A causes privacy invasion to happen frequently.

It is showed the life expectancy had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame . It's really the truth. Our government has already done something. However, it doesn't seem to work so well. "Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine," said Chen Yuyu of Beijing University, one of researchers of this study. Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating. Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed. "We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves," Li Hongbin, another researcher of the study said. Options: A Air pollution in North China is caused by waste gas. B To save the environment, our government should do something more. C The temperature becomes higher and higher in North China.
