input question: Write a multi-choice question for the following article: Article: Let us begin by saying what does not cause our dreams. Our dreams do not come from "another world ". They are not messages from outside source. They are not a look into the future , either . All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind .If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today. So the subject of your dream usually comes from something that has effect on you while you are sleeping (feeling of cold, a noise, a discomfort, etc.) and it may also use your past experiences and the wishes and the interests you have now.This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom. To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment.A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton.He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands! There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean.Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem.They believe that dreams are mostly expressions of wishes that do not come true.In other words, dreams are a way of having your wishes carried out.???

Write a multi-choice question for the following article: Article: In 1800, only three percent of the world's population lived in cities. Only one city -- Beijing -- had a population of over a million. Most people lived in rural areas, and never saw a city in their lives. In 1900, just a hundred years later, roughly 150 million people lived in cities, and the world's ten largest cities all had populations exceeding one million. By 2000, the number of city dwellers exceeded three billion; and in 2008, the world's population crossed a tipping point -- more than half of the people on Earth lived in cities. By 2050, that could increase to over two-thirds. Clearly, humans have become an urban species. In the 19th and early 20th centuries, many people viewed cities negatively -- crowded, dirty environments full of disease and crime. They feared that as cities got bigger, living conditions would worsen. In recent decades, however, attitudes have changed. Many experts now think urbanization is good news, offering solutions to the problems of Earth's growing population. Harvard economist Edward Glaeser, author of The Victory of the Cir, is one such person. Glaeser argues that cities are very productive because "the absence of space between people" reduces the cost of transporting goods, people, and ideas. While the flow of goods has always been important to cities, what is most important today is the flow of ideas. Successful cities enable people to learn from each other easily, and attract and reward smart people with higher wages. Another urbanization supporter is environmentalist Stewart Brand. Brand believes cities help the environment because they allow haft of the world's population to live on about four percent of the land. This leaves more space for open country, such as farmland. City dwellers also have less impact per person on the environment than people in the countryside. Their roads, sewers, and power lines need fewer resources to build and operate. City apartments require less energy to heat, cool, and light. Most importantly, people in cities drive less so they...

Problem: Given the question: Write a multi-choice question for the following article: Article: Plants may not have eyes and ears,but they can recognize their siblings ,and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete . Canadian researchers published that sea rocket,a common seashore plant,can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil,they "play nice" and don't send out more roots to compete.However,the moment one of the plants is thrown in with strangers,it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil. After reading Dudley's study,Bais decided to find the method behind the sibling recognition.Working in his laboratory,Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments,young seedlings were exposed to liquid media containing the root secretions from siblings,from strangers,or only their own secretions.The length of the longest lateral root was measured.The exposure of plants to the root secretions of strangers induced greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter,because so much of their energy is directed at root growth.Because siblings aren't competing against each other,their roots are often much shallower . Biedrzycki did the _ laboratory research,observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns."Arabidopsis roots are nearly translucent when they are young and were also twisted when I removed them from plates,"Biedrzycki notes."This manuscript is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions." The research also may have implications for the home gardener."Often we'll put plants in the ground next to each other and when they don't do well,we blame the...
