TASK 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.
PROBLEM: Article: Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns about spying and other problems.
Answer: Helping us learn more about the earth's atmosphere.

SOLUTION: What's the purpose of Google's Project Loon?

PROBLEM: Article: Check out our tsunami facts and learn some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some recent examples of tsunamis that have occurred around the globe. The Japanese word for tsunami means harbor wave. Tsunamis are sometimes called tidal waves but this term has fallen out of favour because tsunamis are not related to tides. Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions. As a tsunami approaches the shore, water may move back from the coast. If it is shallow enough the water may be pulled back hundreds of metres. If you are in the area, you can know that a tsunami is on the way when you see this phenomenon. Regions in tsunami danger zones often have warning systems in place to give people as much time as possible to move to a safe place. When tsunamis hit shallow water (often near the coast) they slow down but increase in height. An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200,000 people in 14 countries. In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15,000 people. The tsunami waves created by the Tohoku earthquake reached a height of over 40 metres in some areas, wiping out coastal towns and causing a number of nuclear accidents.
Answer: Four.

SOLUTION: How many causes of tsunamis are mentioned in the text?

PROBLEM: Article: Dr. Paul Kelly, head of Monkeseaton Community High School in North Tyneside, said it would mean the end of sleeping in lessons before lunch, after experiments showed teenagers could have different body clocks from adults and younger children. Russell Foster, an Oxford professor of neuroscience , tested the memory of 200 Monkseaton pupils at 9 am and 2 pm using pairs of words, and discovered a 9% improvement in the afternoon. Students correctly identified 51% of word pairs in the latest session, compared with 42% in the morning. Tayler McCullough, 15, one of the test subjects, said the majority of students would welcome the extra hours in bed, "I'm extremely hard to get up in the morning. One or two people like to get to school early, but most of us would be up for going in later. I'm sure it would make a big difference to our learning ability." Kelly is _ that a change of school timetable will have a meaningful effect on exam performance. He wants his school's governors to approve his plan and put the new time-table in place before the opening of Monkseaton's new timetable in place before the opening of Monkseaton's new school building, the most technologically advanced in the country, in September. Kelly hopes his latest idea will be just as successful. "We have to be practical. But this proves that, by starting later, children's learning improves, as does their health." Foster said, "This is preliminary data, but what's exciting is that it matches more detailed studies carried out in Canada and the US. Teenagers get up late not because they are lazy but because they are biologically programmed to do so."
