Input: Bacteria
Certain bacteria form close spatial associations that are essential for their survival. One such mutualistic association, called interspecies hydrogen transfer, occurs between clusters of anaerobic bacteria that consume organic acids, such as butyric acid or propionic acid, and produce hydrogen, and methanogenic Archaea that consume hydrogen. The bacteria in this association are unable to consume the organic acids as this reaction produces hydrogen that accumulates in their surroundings. Only the intimate association with the hydrogen-consuming Archaea keeps the hydrogen concentration low enough to allow the bacteria to grow.

What kind of bacteria can form interspecies hydrogen transfer?
Output: anaerobic bacteria

Input: Dwight D. Eisenhower
Early in 1953, the French asked Eisenhower for help in French Indochina against the Communists, supplied from China, who were fighting the First Indochina War. Eisenhower sent Lt. General John W. "Iron Mike" O'Daniel to Vietnam to study and assess the French forces there. Chief of Staff Matthew Ridgway dissuaded the President from intervening by presenting a comprehensive estimate of the massive military deployment that would be necessary. Eisenhower stated prophetically that "this war would absorb our troops by divisions."

Who was providing supplies to the Vietnamese communists fighting against France?
Output: China

Input: Lancashire
During the 20th century, the county became increasingly urbanised, particularly the southern part. To the existing county boroughs of Barrow-in-Furness, Blackburn, Bolton, Bootle, Burnley, Bury, Liverpool, Manchester, Oldham, Preston, Rochdale, Salford, St Helens and Wigan were added Blackpool (1904), Southport (1905), and Warrington (1900). The county boroughs also had many boundary extensions. The borders around the Manchester area were particularly complicated, with narrow protrusions of the administrative county between the county boroughs Lees urban district formed a detached part of the administrative county, between Oldham county borough and the West Riding of Yorkshire.

When was Southport added?
Output: 1905

Input: Slavs
Because of the vastness and diversity of the territory occupied by Slavic people, there were several centers of Slavic consolidation. In the 19th century, Pan-Slavism developed as a movement among intellectuals, scholars, and poets, but it rarely influenced practical politics and did not find support in some nations that had Slavic origins. Pan-Slavism became compromised when the Russian Empire started to use it as an ideology justifying its territorial conquests in Central Europe as well as subjugation of other ethnic groups of Slavic origins such as Poles and Ukrainians, and the ideology became associated with Russian imperialism. The common Slavic experience of communism combined with the repeated usage of the ideology by Soviet propaganda after World War II within the Eastern bloc (Warsaw Pact) was a forced high-level political and economic hegemony of the USSR dominated by Russians. A notable political union of the 20th century that covered most South Slavs was Yugoslavia, but it ultimately broke apart in the 1990s along with the Soviet Union.

When did Pan-Slavism develop as a movement?
Output:
In the 19th century
