TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
PROBLEM: Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.
Answer: the living standard of the world's population will improve greatly

SOLUTION: According to the passage, in 2100 while output of food will be greater, _ .

PROBLEM: Article: About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels on the ground rather than the roof. Then they began to develop the Solar Roadway. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways. Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions _ need. According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots. The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring .
Answer: costs no more money than current roads

SOLUTION: In the inventors' opinion, the Solar Roadway _ .

PROBLEM: Article: Perhaps you have been told about some habits which stop a person reading fast, and have been strongly asked to break those habits which you might have. Do you still have any of these bad habits7 Check yourself by answering "yes" or "no" to these questions: 1. Do you move your lips when reading silently? 2. Do you point to words with your finger as you read? 3. Do you move your head from side to side as you read? 4. Do you read one word at a time? If you answer "yes" to any of these questions, start at once to break the habit. If you move your lips, hold your fingers over them, or hold a piece of paper between your lips while you are reading. Then if your lips move, you will know it and can stop them. If you point to words, hold the two sides of your book, one side with your left hand, the other side with your right hand. Then you will not have a free finger to use in pointing while reading. If you move your head, place your chin in one hand, and hold your head still(,). If you read no more than one or two or three words at a time, you need to work very hard in learning to take in more words at each glance as your eyes travel across the lines of words.
Answer: to feel whether y our lips move or not

SOLUTION:
You may hold your fingers over your lips while reading _
