Part 1. Definition
In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
Part 2. Example
Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Answer: How many books are there in the British Library?
Explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.
Part 3. Exercise
Article: Pollution's great effects on the environment have become more obvious in recent years, resulting in a movement to make best use of energy, depend less on fossil fuels, and to cut down air and water pollution. Most scientists agree that such changes are necessary to protect our environment from further harm. The construction industry uses up a large quantity of energy and resources and creates a huge amount of pollution. In the United States, building takes up 39% of the country's total energy use, 12% of total water use, 68% of total electricity use, and 38% of carbon dioxide emissions , according to the Environment Protection Agency. Green buildings use less energy, water, create less waste, and are healthier to live, work, or go to school in than standard buildings. Green buildings use resources more properly during the entire building cycle than traditional building. The environmental benefits of building green include the protection of ecosystems , improved air and water quality, less waste flowing into streams, and the protection of natural resources. Green buildings can also result in lower operating costs because they use less energy and materials and improve indoor air quality, which improves the health of those who live in such buildings. The process of building green includes technical and aesthetic planning with nature protection in mind. Building designs often mirror the surrounding environment and natural resources and use building materials that can be reused. In addition, recycled resources that are found locally are used for green buildings, diminishing the cost and air pollution related with transporting materials over long distances. Careful selection of the building place is important to reduce human effect on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool wind and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small. Besides, green roofs can be built to reduce energy use and cost. These roofs are partly or completely covered with vegetation, which helps reduce heating and cooling costs, prevent storm-water runoff, and so on. Other advantages of green buildings often include energy and water saving, recycling, and waste reduction. What's more, energy sources such as solar power and wind power are used for heat and electricity, which reduces costs and the effect on the environment.
Answer: To encourage the application of green building.
