Input: Article: As of 2008[update], geothermal power development was under way in more than 40 countries, partially attributable to the development of new technologies, such as Enhanced Geothermal Systems. The development of binary cycle power plants and improvements in drilling and extraction technology may enable enhanced geothermal systems over a much greater geographical range than "traditional" Geothermal systems. Demonstration EGS projects are operational in the USA, Australia, Germany, France, and The United Kingdom.

Now answer this question: What is one new technology attributed to the growth of geothermal power?

Output: Enhanced Geothermal Systems

Input: Article: Tennessee is known as the "Volunteer State", a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee, especially during the Battle of New Orleans. Other sources differ on the origin of the state nickname; according to the Columbia Encyclopedia, the name refers to volunteers for the Mexican–American War. This explanation is more likely, because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican-American War resulted in 30,000 volunteers from Tennessee alone, largely in response to the death of Davy Crockett and appeals by former Tennessee Governor and now Texas politician, Sam Houston.

Now answer this question: By what nickname is Tennessee officially known?

Output: Volunteer State

Input: Article: As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream. As of May 27, 2008, 34 lakes had formed due to earthquake debris blocking and damming rivers, and it was estimated that 28 of them were still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.

Now answer this question: What formed behind blockages?

Output:
quake lakes
