Please answer this: Extract the answer to the question from the following context. Question: Where does the Speaker work? Context: Internal party disunity compounded the difficulty of identifying lawmakers who might have informally functioned as a minority leader. For instance, "seven of the fourteen speakership elections from 1834 through 1859 had at least twenty different candidates in the field. Thirty-six competed in 1839, ninety-seven in 1849, ninety-one in 1859, and 138 in 1855." With so many candidates competing for the speakership, it is not at all clear that one of the defeated lawmakers then assumed the mantle of "minority leader." The Democratic minority from 1861 to 1875 was so completely disorganized that they did not "nominate a candidate for Speaker in two of these seven Congresses and nominated no man more than once in the other five. The defeated candidates were not automatically looked to for leadership."

Problem: Extract the answer to the question from the following context. Question: What is a specific type of way you could identify a perfective verb? Context: The verbs of most aspect pairs differ in one of two ways: by prefix or by suffix. In prefix pairs, the perfective verb has an added prefixfor example, the imperfective psat (to write, to be writing) compared with the perfective napsat (to write down, to finish writing). The most common prefixes are na-, o-, po-, s-, u-, vy-, z- and za-. In suffix pairs, a different infinitive ending is added to the perfective stem; for example, the perfective verbs koupit (to buy) and prodat (to sell) have the imperfective forms kupovat and prodavat. Imperfective verbs may undergo further morphology to make other imperfective verbs (iterative and frequentative forms), denoting repeated or regular action. The verb jit (to go) has the iterative form chodit (to go repeatedly) and the frequentative form chodivat (to go regularly).

A: (to write down, to finish writing)
Problem: Given the question: Extract the answer to the question from the following context. Question: What standard image format is mentioned here? Context: Video data may be represented as a series of still image frames. The sequence of frames contains spatial and temporal redundancy that video compression algorithms attempt to eliminate or code in a smaller size. Similarities can be encoded by only storing differences between frames, or by using perceptual features of human vision. For example, small differences in color are more difficult to perceive than are changes in brightness. Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression. Some of these methods are inherently lossy while others may preserve all relevant information from the original, uncompressed video.

The answer is:
JPEG
input question: Extract the answer to the question from the following context. Question: What inaugural happening resulted in restrictions on the amount of output a hand was required to devote to his craft? Context: These immigrants were largely responsible for the first general strike in North America in 1835, in which workers in the city won the ten-hour workday. The city was a destination for thousands of Irish immigrants fleeing the Great Famine in the 1840s; housing for them was developed south of South Street, and was later occupied by succeeding immigrants. They established a network of Catholic churches and schools, and dominated the Catholic clergy for decades. Anti-Irish, anti-Catholic Nativist riots had erupted in Philadelphia in 1844. In the latter half of the century, immigrants from Russia, Eastern Europe and Italy; and African Americans from the southern U.S. settled in the city. Between 1880 and 1930, the African-American population of Philadelphia increased from 31,699 to 219,559. Twentieth-century black newcomers were part of the Great Migration out of the rural South to northern and midwestern industrial cities.???
output answer: first general strike in North America
Extract the answer to the question from the following context. Question: What vehicle can you travel by air to another state in? Context: The constraints of constructing a flight deck affect the role of a given carrier strongly, as they influence the weight, type, and configuration of the aircraft that may be launched. For example, assisted launch mechanisms are used primarily for heavy aircraft, especially those loaded with air-to-ground weapons. CATOBAR is most commonly used on USN supercarriers as it allows the deployment of heavy jets with full loadouts, especially on ground-attack missions. STOVL is used by other navies because it is cheaper to operate and still provides good deployment capability for fighter aircraft.

Answer: aircraft
Q: Extract the answer to the question from the following context. Question: __ remained German until the end of World War I, when it reverted to France. Context: The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Chalons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war.
A:
Metz
