Input: Consider Input: Paragraph- Sent 1: The mighty fane, with its three massive towers, rises majestically over the red roofs of the town.
Sent 2: Its most striking feature is the great Norman screen, running up without buttresses or projections to the parapet and hiding the bases of the square, richly decorated towers of the west front.
Sent 3: The plain centre of the screen is the work of Remigius, the first bishop.
Sent 4: The rest of it is relieved with rich arcading of Late Norman and Early English periods.
Sent 5: The wooden spires which crowned the towers were removed in 1807.
Sent 6: In 1192 Hugh of Avalon determined to rebuild the Norman building of Remigius, which an earthquake had shaken.
Sent 7: To him we owe the choir and eastern transept.
Sent 8: His successors completed the western transept and began the west end of the nave.
Sent 9: So much money had to be spent in rebuilding the central tower, which fell in 1239, that the canons could not rebuild the nave entirely, but had to incorporate the Norman end by Remigius.
Sent 10: Unfortunately the axis of the west front does not correspond to that of the nave, which is too wide for its height.
Sent 11: The low vaulting is a serious defect in the choir built by St. Hugh, but of the superb beauty of the Angel Choir, which encloses his shrine, there can be no doubt.
Sent 12: In its richness of sculpture it is one of the masterpieces of Gothic architecture in England.
Sent 13: The interior of the cathedral is remarkable for the harmony of its style, which is Lancet-Gothic, and the dim lighting of the nave only adds to its impressiveness.
Question: What was atop the three towers?.

Output: Wooden spires.

Input: Consider Input: Paragraph- Sent 1: You couldnt survive without your skin.
Sent 2: It has many important functions.
Sent 3: The main function of the skin is controlling what enters and leaves the body.
Sent 4: It prevents the loss of too much water from the body.
Sent 5: It also prevents bacteria and other microorganisms from entering the body.
Sent 6: The skin helps maintain a constant body temperature.
Sent 7: It keeps the body cool in two ways.
Sent 8: Sweat from sweat glands in the skin evaporates to cool the body.
Sent 9: Blood vessels in the skin dilate, or widen.
Sent 10: This action increases blood flow to the body surface.
Sent 11: This allows more heat to reach the surface.
Sent 12: The heat is then able to radiate off the body.
Sent 13: The opposite happens to retain body heat.
Sent 14: Blood vessels in the skin constrict, or narrow.
Sent 15: This decreases blood flow to the body surface.
Sent 16: This reduces the amount of heat that reaches the surface.
Sent 17: When this happens, less heat can be lost to the air.
Question: What is different when something constricts as compared to when it dilates?.

Output: Diameter.

Input: Consider Input: Paragraph- Sent 1: As noted above, the 9/11 plotters spent somewhere between $400,000 and $500,000 to plan and conduct their attack.
Sent 2: The available evidence indicates that the 19 operatives were funded by al Qaeda, either through wire transfers or cash provided by KSM, which they carried into the United States or deposited in foreign accounts and accessed from this country.
Sent 3: Our investigation has uncovered no credible evidence that any person in the United States gave the hijackers substantial financial assistance.
Sent 4: Similarly, we have seen no evidence that any foreign government-or foreign government official-supplied any funding.
Sent 5: We have found no evidence that the Hamburg cell members (Atta, Shehhi, Jarrah, and Binalshibh) received funds from al Qaeda before late 1999.
Sent 6: It appears they supported themselves.
Sent 7: KSM, Binalshibh, and another plot facilitator, Mustafa al Hawsawi, each received money, in some cases perhaps as much as $10,000, to perform their roles in the plot.
Sent 8: After the Hamburg recruits joined the 9/11 conspiracy, al Qaeda began giving them money.
Sent 9: Our knowledge of the funding during this period, before the operatives entered the United States, remains murky.
Sent 10: According to KSM, the Hamburg cell members each received $5,000 to pay for their return to Germany from Afghanistan after they had been selected to join the plot, and they received additional funds for travel from Germany to the United States.
Sent 11: Financial transactions of the plotters are discussed in more detail in chapter 7.
Sent 12: Requirements for a Successful Attack As some of the core operatives prepared to leave for the United States, al Qaeda's leaders could have reflected on what they needed to be able to do in order to organize and conduct a complex international terrorist operation to inflict catastrophic harm.
Sent 13: We believe such a list of requirements would have included leaders able to evaluate, approve, and supervise the planning and direction of the operation; communications sufficient to enable planning and direction of the operatives and those who would be helping them; a personnel system that could recruit candidates, vet them, indoctrinate them, and give them necessary training; an intelligence effort to gather required information and form assessments of enemy strengths and weaknesses; the ability to move people; and the ability to raise and move the necessary money.
Sent 14: The information we have presented about the development of the planes operation shows how, by the spring and summer of 2000, al Qaeda was able to meet these requirements.
Sent 15: By late May 2000, two operatives assigned to the planes operation were already in the United States.
Sent 16: Three of the four Hamburg cell members would soon arrive.
Question: After what time would three of four Hamburg cell members soon arrive?.
Output: After May 2000.
