[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins can't carry all this sugar away, so the leaves change the sugar into starch , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem and in leaves, fruits and seeds. Options: A How green plants make food. B How green plants make sugar. C How green plants get their energy. D How green plants change sugar into starch. Answer: A How green plants make food. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Over thousands of years, human beings have been learning about more and more about this world, and have figured out many ways to avoid risks and make our lives easier. Even in ancient times, we used fire to frighten away animals, built simple boats to cross waters, and armed ourselves with sharpening stones and sticks. Nowadays, with advanced technology and instrument, people know the world better than ever. It's surprising how much people already know about this world and how much we've changed our lives by using the knowledge we have. But if you think we know everything, that's wrong. I guess sometimes we have to accept the limitation on our understanding of the world. No matter how much we're already known about the world, there are things that remain mysterious. I learned this from my pregnancy which ended in the 6th month, due to a placental abruption . I started to see my OB/GYN every month, taking vitamins regularly, doing all the lab tests to make sure we were expecting a healthy baby. All the results looked promising, and we thought we would have a healthy baby girl in January next year. Even in the week before placental abruption, when I was in hospital because of a sudden bleeding, doctors didn't believe there were any bad possibilities after reading my blood tests. Unfortunately it still happened. Later, I asked my doctor "So what caused this?" She said, "I don't know. We probably will never know." After leaving the hospital, I sometimes do feel frustrated for what happened. But I already accept the fact that there are simply things that we do not know. No matter how well you plan and monitor your life there are uncertainties that can not be predicted and thus can not be avoided. _ Her name was Janet.

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: On the day after Thanskgiving in the US, or Black Friday, lots of stores offer special discounts to mark the beginning of holiday shopping season. In China, a similar day falls on Nov. 11 when millions of Chinese shoppers go to Tmall.com and Taobao.com, two e-commerce websites operated by Alibaba. The 11.11 Shopping Festival, as the event is now called, is also known in China as Singles Day. The shopping festival first started in 2009 and Alibaba said it chose the date because it was easy to remember. Last year, Tmall and Taobao together produced 19.1 billion in sales on that day, according to Alibaba. This year's shopping festival kicked off with an even stronger start--sales hit 100 million yuan 55 seconds after midnight and reached 35 billion at the end of the day. The shopping spree drew the attention of China's leaders, as Premier Li Keqiang recently praised Alibaba's founder, Jack Ma, for creating a day for consumption. China is trying to lead the country's economy to a slower, more sustainable growth model based on domestic consumption instead of investment and exports. Online shopping is no doubt a growth point that will release spending potential. China had 564 million regular Internet users by the end of last year. It has surpassed the US to become the world's largest e-commerce market, with its online sales over 1 trillion US dollars (6 trillion yuan) by 2020. "The real-time nature of online consumption attracts millions of people to spend money and enjoy life. E-commerce opens a new channel for China to encourage domestic demand," Liu Yin, vice-president of the China International Electronic Commerce Center said. More importantly, it promotes employment and the logistics industry with its sales model of "online purchasing plus express delivery", he added. Convenience, choice and low prices have increased online shopping, but there are still some problems with the one-day shopping spree. Some online shops, driven by the huge profits, took this opportunity to play price tricks. They raised...
