Detailed Instructions: 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.
See one example below:
Problem: 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.
Solution: 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.

Problem: Article: By 2050, half of the world's population will live in the tropics--the  ly warm belt that circles the globe--according to State of the Tropics, a report released today. Rapid population growth, along with economic growth, means that the region's influence will grow in coming decades, the authors of the 500-page work predict. The project, first launched in 2011, aimed to answer one significant question: Is life in the tropics improving? To find out, the researchers analyzed environmental, social, and economic indicators collected over 6 decades. It finds that the region has made "extraordinary progress" in many areas. For example, more people have access to safe drinking water, and the number of protected areas is increasing. The tropics also have outperformed the rest of the world in economic growth over the past 30 years. However, some challenges remain. Investment in research and development, for example, has increased cautiously, but tropical nations still invest less than the rest of the world. "As a proportion of GDP the Rest of the World invests almost four times as much in research and development than the Tropics." concludes the report. The report also includes a new analysis of how climate change will affect the region. Many plant and animal species are moving poleward in an attempt to stay within their preferred environmental conditions in the tropics, the authors write. However, some organisms may not be able to keep pace with the changing conditions, they predict. As a result, they can experience population declines or go extinct. In addition, an expanded tropical zone also threatens health and safety issues, the authors warn. As regions become more suitable to insects such as mosquitoes and ticks, the spread of insect-borne diseases such as malaria, dengue, and Lyme disease could rise, causing a burden to human health and the economy.  Bruna, a researcher, says he sees a lot to be concerned about in the report. "While we've made incredible advances in some areas, I think the risks for the tropics that are highlighted in this report are things that we really need to be concerned about." 
 Answer: To answer if life in the tropics is improving.
Solution:
What was the original purpose of the project State of the Tropics?
