Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan's voice is heard every day on the net -- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on You Tube --lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free. Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his "Khan Academy" four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan's help, the cousin got good at math, and Khan began a new career. Now, Khan records his lessons himself, but he never goes on camera. "It feels like my voice in their head. You're looking at it and it feels like someone's over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you," he said. When Springfield High School in Palo Alto, California invited Khan to speak in person--he immediately connected to the students there. The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. "I think the teachers are good, but they can't teach at a speed that's perfect for everyone," she said. "I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it." Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. "Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off," he said. For Khan, teaching math, science, and finance is just the beginning. He says he's ready to expand his YouTube site to include other... Options: A His success in helping his cousin learn math. B His discovery that many students found learning math difficult. C A suggestion made to him at a local high school. D His interest in Internet teaching. Answer: A His success in helping his cousin learn math. Question:

The answer is:
What gave Khan the idea of teaching math online?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Are you a forgetful person? You might be able to blame your genes, a new study in the journal Neuroscience Letters suggests. Researchers from the University of Bonn have identified a variant on the DRD2 gene that seems to be associated with increased forgetfulness. Everyone has one of two variants of the DRD2 gene, the difference is just one letter in the genetic code: Some people have the cytosine (C) variant, while others have the thymine (T) variant. The researchers wanted to see how having one variant over another was associated with forgetfulness. To test this, they analyzed the DRD2 gene of 500 study participants, and also had the participants answer surveys about their forgetfulness (such as how often they misplaced their keys, or forgot names). Most of the study participants--three quarters of them--had the thymine gene variant, while the other quarter had the cytosine gene variant. Researchers found an association between more forgetfulness problems and having the thymine gene variant of DRD2. Meanwhile, the cytosine gene variant seemed to have a protective effect against forgetfulness. However, "there are things you can do to compensate for forgetfulness; writing yourself notes or making more of an effort to put your keys down in a specific location--and not just anywhere," study researcher Dr. Sebastian Markett, of the University of Bonn, said in a statement. Research has also suggested that some age groups are more forgetful than others. A recent national poll showed that millenials, who were born between the early 1980s and the early 2000s, are actually more likely than seniors to be absent-minded with things like what day of the week it is, where they put their keys and remembering to bring their lunch. Meanwhile, another study recently published in the journal BMC Psychology showed that men are more likely than women to experience minor memory problems. Options: A Health. B Nature. C People. D Science Answer: D Science Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Mobile communications and the IP phone business have gradually replaced traditional long-distance calls. Mobile communications account for 28.5 percent of the total long-distance communications business. IP phones have 41.4 percent, while traditional long-distance calls are down to 30.1 percent. China Mobile, the country's largest mobile communication operator, has accounted for nearly 40 percent of taxes in the domestic telecom market. That puts it at the top of the six major telecom operators in the nation, according to the latest official statistics. The other five are: China Telecom, 31.1 percent; China Netcom, 16.6 percent; China Unicom, 13.4 percent; China Satellite Communications Corp and China Railcom, 1.5 percent. China Mobile is being chased by smaller rivals China Unicom and China Telecom, both of which are making significant 3G subscriber gains. That's aided in no small part by deals to offer the iPhone. However, as of March, China Mobile did have 15 million iPhone users on its network. In another ranking, Xiaomi, Huawei, Lenovo, vivo and OPPO came in as the top five mobile phone sellers in China by April, 2015, according to IHS Technology. The report also says that during this period, China produced 82 million handsets. (including GSM, GPRS and CDMA phones) and sold 80 million. Of the phones sold, 37 million were exported to other countries. Analysts point out that China's lack of core technologies and its heavy reliance on overseas technologies have proved to be an obstacle for development of domestic phone makers. Options: A most phones are sold in foreign countries B most long-distance calls are made through mobile phone today C China had the most mobile phone users D China Telecom brings in more taxes of all the companies Answer: B most long-distance calls are made through mobile phone today Question:
