Input: Catalan language
Catalan bears varying degrees of similarity to the linguistic varieties subsumed under the cover term Occitan language (see also differences between Occitan and Catalan and Gallo-Romance languages). Thus, as it should be expected from closely related languages, Catalan today shares many traits with other Romance languages.

What are there besides degrees of similarity with Occitan?
Output: differences

Input: Buddhism
According to East Asian and Tibetan Buddhism, there is an intermediate state (Tibetan "bardo") between one life and the next. The orthodox Theravada position rejects this; however there are passages in the Samyutta Nikaya of the Pali Canon that seem to lend support to the idea that the Buddha taught of an intermediate stage between one life and the next.[page needed]

There is an intermediate state between one life and the next according to what Buddism?
Output: East Asian and Tibetan

Input: Electric motor
In 1886, Frank Julian Sprague invented the first practical DC motor, a non-sparking motor that maintained relatively constant speed under variable loads. Other Sprague electric inventions about this time greatly improved grid electric distribution (prior work done while employed by Thomas Edison), allowed power from electric motors to be returned to the electric grid, provided for electric distribution to trolleys via overhead wires and the trolley pole, and provided controls systems for electric operations. This allowed Sprague to use electric motors to invent the first electric trolley system in 188788 in Richmond VA, the electric elevator and control system in 1892, and the electric subway with independently powered centrally controlled cars, which were first installed in 1892 in Chicago by the South Side Elevated Railway where it became popularly known as the "L". Sprague's motor and related inventions led to an explosion of interest and use in electric motors for industry, while almost simultaneously another great inventor was developing its primary competitor, which would become much more widespread. The development of electric motors of acceptable efficiency was delayed for several decades by failure to recognize the extreme importance of a relatively small air gap between rotor and stator. Efficient designs have a comparatively small air gap. [a] The St. Louis motor, long used in classrooms to illustrate motor principles, is extremely inefficient for the same reason, as well as appearing nothing like a modern motor.

What was the transportation advancement made possible by Sprague's designs?
Output: electric trolley system

Input: Crimean War
In June, the fleets transported the Allied expeditionary forces to Varna, in support of the Ottoman operations on the Danube; in September they again transported the armies, this time to the Crimea. The Russian fleet during this time declined to engage the allies, preferring to maintain a "fleet in being"; this strategy failed when Sevastopol, the main port and where most of the Black Sea fleet was based, came under siege. The Russians were reduced to scuttling their warships as blockships, after stripping them of their guns and men to reinforce batteries on shore. During the siege, the Russians lost four 110- or 120-gun, three-decker ships of the line, twelve 84-gun two-deckers and four 60-gun frigates in the Black Sea, plus a large number of smaller vessels. During the rest of the campaign the allied fleets remained in control of the Black Sea, ensuring the various fronts were kept supplied.

Where was the port where most of the Black Sea fleet was located?
Output:
Sevastopol
