Input: Geological history of Earth
A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.

What was on the land at 30 degrees latitude north in the carboniferous period?
Output: lush coal swamps

Input: Geography of the United States
The five Great Lakes are located in the north-central portion of the country, four of them forming part of the border with Canada, only Lake Michigan situated entirely within United States. The southeast United States contain subtropical forests and, near the gulf coast, mangrove wetlands, especially in Florida. West of the Appalachians lies the Mississippi River basin and two large eastern tributaries, the Ohio River and the Tennessee River. The Ohio and Tennessee Valleys and the Midwest consist largely of rolling hills and productive farmland, stretching south to the Gulf Coast.

Which major river is located west of the Appalachian mountains?
Output: Mississippi River

Input: Pacific War
By April 1945, China had already been at war with Japan for more than seven years. Both nations were exhausted by years of battles, bombings and blockades. After Japanese victories in Operation Ichi-Go, Japan were losing the battle in Burma and facing constant attacks from Chinese Nationalists forces and Communist guerrillas in the country side. The Japanese army began preparations for the Battle of West Hunan in March 1945. Japanese mobilized 34th, 47th, 64th, 68th and 116th Divisions, as well as the 86th Independent Brigade, for a total of 80,000 men to seize Chinese airfields and secure railroads in West Hunan by early April. In response, the Chinese National Military Council dispatched the 4th Front Army and the 10th and 27th Army Groups with He Yingqin as commander-in-chief. At the same time, it airlifted the entire Chinese New 6th Corps, an American-equipped corps and veterans of the Burma Expeditionary Force, from Kunming to Zhijiang. Chinese forces totaled 110,000 men in 20 divisions. They were supported by about 400 aircraft from Chinese and American air forces. Chinese forces achieved a decisive victory and launched a large counterattack in this campaign. Concurrently, the Chinese managed to repel a Japanese offensive in Henan and Hubei. Afterwards, Chinese forces retook Hunan and Hubei provinces in South China. Chinese launched a counter offensive to retake Guangxi which was the last major Japanese stronghold in South China. In August 1945, Chinese forces successfully retook Guangxi.[citation needed]

Who was the Chinese commander-in-chief of the 10th and 27th Army Groups?
Output: He Yingqin

Input: New York City
New York City has focused on reducing its environmental impact and carbon footprint. Mass transit use in New York City is the highest in the United States. Also, by 2010, the city had 3,715 hybrid taxis and other clean diesel vehicles, representing around 28% of New York's taxi fleet in service, the most of any city in North America.

What percentage of the New York City cab fleet was clean diesel or hybrid in 2010?
Output:
28%
