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.

Input: Consider Input: Article: The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research There are people who claim that SPS is unrealistic - because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple. Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further. We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades - such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy.
Answer: The Future Energy- SPS

Output: Which of the following may be the best title for the passage?

Input: Consider Input: Article: No one knows exactly when jazz was invented, or by whom. But it is said that it began in the early 1900s. Jazz was a new kind of music, for America and the world, and New Orleans was its birthplace. Who were the jazz pioneers? Most were blacks. This music was not written down, and at first only blacks played it. It was hard for white musicians to learn the new style. But soon they, too, were playing jazz. The popularity of this music spread. From New Orleans, it traveled up the Mississippi to Chicago, then to Kansas City and New York. By the 1920s, there were many jazz musicians, both black and white. Many of them were famous. One man was better than the rest. His name was Louis Armstrong. Louis Armstrong was a born musician. He was not only talented but also hard-working. He also had a good sense of humor and a big, good-natured smile. These personal qualities were valuable in his rise to fame. After he became famous, he traveled around the world. It seemed that everyone wanted to hear Louis play. But life was not always easy, especially at the beginning. Louis Armstrong was born in 1900 in New Orleans. His father never went to school and his mother could hardly read. When Louis was still a kid, his parents separated, and Louis lived with his mother. How hard their life was can readily be imagined. And yet Louis smiled through everything. He later wrote, "My whole life has been happiness. Life was there for me and I accepted it. Whatever happened has been beautiful to me. I love everybody."
Answer: His talent and hard work.

Output: What made Louis Armstrong become the best jazz musician?

Input: Consider Input: Article: The shocking collapse of one of the West Coast's biggest wild salmon runs has prompted even cash-trapped fishermen to call for an unprecedented shutdown of salmon fishing off the coasts of California and Oregon. The Sacramento River salmon run is usually one of the most productive on the Pacific Coast,providing the bulk of the salmon caught by sport and commercial trollers off California and Oregon. But only about 90,000 adult salmon returned to the Central Valley last fall--the second lowest number on record and well below the number needed to maintain a healthy fishery.That number is projected to fall to a record low of58.000 this year. The council,which regulates Pacific Coast fisheries,will choose between three management options:a total ban on salmon fishing off the coast of California and Oregon;extremely limited fishing in select areas;or catch-and-release fishing for scientific research. For consumers,it will be hard to find any Chinook,also known as king salmon.which are prized by trollers,seafood critics and upscale restaurants.There should still be abundant supplies of farm-raised salmon.but prices could be higher. Biologists and others are trying to figure out what caused the salmon collapse so they can make sure California's Chinook populations rebound. There are many potential factors,because wild salmon are born in streams and rivers, migrate to the ocean when they're juveniles and spend two to four years there before returning to spawn in the areas where they were born.In between they have to navigate the often dangerous waters of the Sacramento Delta and San Francisco Bay. The council has asked state and federal scientists to research possible causes, including water diversions,habitat destruction,dam operations,agricultural pollution,and ocean conditions.Many scientists point out that unusual weather patterns disrupted the marine food chain along the Pacific Coast in 2005,when thousands of seabirds washed up dead or starving because they couldn't find enough to eat. Researchers believe those poor ocean conditions also devastated the juvenile salmon that would have returned to the Central Valley last year.Young Chinook couldn't find the tiny shrimp and fish they depend onto survive.
Answer: Last fall,there was the second lowest number of grown salmon returning on record.
