Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Most earthquakes occur within the upper 15 miles of the earth's surface, but earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set , it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir was not strong, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result. There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic sea waves, or tsunamis . These are often called tidal waves, but the name is incorrect. They had nothing to do with tides. In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them "tsunamis" meaning "harbor waves", because they reach a sizable height only in harbors. Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An earthquake warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground: There is no way to stop the oncoming wave. Options: A help reduce fear B find ways to stop them C be warned early enough D develop warning systems Answer: C be warned early enough Question:

A: The significance of the slow speed of tsunamis is that people may _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Zhang Wenchi is a 19-year-old student of Hubei Xiangyang No.1 High School. He is very brave and always helps others in need. On March 26, 2012, Zhang donated bone marrow at the Navy General Hospital of Beijing. He is the youngest and the first high school student to do it. Last April, Zhang became a blood donor on his 18th birthday. He also joined the China Marrow Donor Program that day. Six months later, his bone marrow was chosen as a match for a 4-year-old leukemia patient from Fujian. Zhang was studying for the National College Entrance Examination (NCEE) when the call from the Chinese Bone Marrow Donors came. He found out that the patient could not wait, or things might get worse. With the support of his family and school, Zhang arrived at the hospital in Beijing the very next day. "Saving a life is more important than taking an exam, and having the chance to help cure a patient does not allow for more thought," Zhang said. The transplant operation was a success. After that, Zhang Wenchi was in good health and he came back to school soon. Zhang said then the most important task for him was the exam. He hoped that his dream of becoming a pilot could come true. Now the NCEE has been over for more than a month, and what about Zhang Wenchi's marks? To our great relief, it's known that he has earned 540 points, which means he can be admitted into Beihang University (formerly Beijing University of Aeronautics & Astronautics). Therefore he can realize his dream of flying in the sky. Zhang's deed has earned him nationwide respect, and some have given him the nickname, "the most beautiful post-90s student". Options: A Zhang Wenchi's college dream B A 19-year-old student gave up exams C A 4-year-old leukemia patient was saved D Zhang Wenchi---the most beautiful post-90s student Answer: D Zhang Wenchi---the most beautiful post-90s student Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: School children are using mobile phone applications to do their homework, which seem to beincreasing during summer vacations. But instead of blaming students for their behavior, we should say noto too much homework. This is important because by using mobile phone applications to do theirhomework, students don't add much to their knowledge, says an article in Guangzhou-based YangchengEvening News. Excerpts : Using mobile phone applications to do homework is no different from copying from someone else'swork. This is the opinion of a vast majority of teachers. Students who seek cell phone apps help to do theirhomework will pay dearly during major exams when they cannot seek the help of such applications, theteachers say. The heavy load of homework Chinese students are burdened with, said to be the heaviest in the world,has led to the popularity of these applications. Senior high school students in China rarely go to bed before 11 pm. A report in Shanghai published in2013 showed that students in the city on average spend 28.2 hours in class every week, the 9th highestamong 65 countries and regions surveyed. Also, they spend an average of 13.8 hours a week doinghomework, most in the world. There is no association between the amount of homework one does and the amount of knowledge onegathers. In fact, a research by Australian experts shows that the result is exactly the opposite: the morehours students spend doing homework, the less effective they will be in gaining knowledge. The United States is one of the countries where students do little homework, but that has not damagedthe country's academic status in the world. So, it's time Chinese schools understood this fact and freed students of the unnecessary burden ofhomework. Options: A Free kids of the burden of homework. B Stop using mobile phones to do homework. C Spend less time to gain much knowledge. D Improve China's academic status in the world. Answer: A Free kids of the burden of homework. Question:
