Input: Read this: The capital city, Washington, District of Columbia, is a federal district located on land donated by the state of Maryland. (Virginia had also donated land, but it was returned in 1849.) The United States also has overseas territories with varying levels of independence and organization: in the Caribbean the territories of Puerto Rico and the U.S. Virgin Islands, and in the Pacific the inhabited territories of Guam, American Samoa, and the Northern Mariana Islands, along with a number of uninhabited island territories.
Question: The District of Columbia is on land donated by what two states?

Output: unanswerable


QUES: The initial cost of an incandescent bulb is small compared to the cost of the energy it uses over its lifetime. Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure. A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems. When used for lighting in houses and commercial buildings, the energy lost to heat can significantly increase the energy required by a building's air conditioning system. During the heating season heat produced by the bulbs is not wasted, although in most cases it is more cost effective to obtain heat from the heating system. Regardless, over the course of a year a more efficient lighting system saves energy in nearly all climates.

Do incandescent lights emit more, less, or the same amount of light as they age?
What is the answer?
ANS: less


QUES: Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring with the major exception being overhead electric power transmission where aluminium is often preferred. Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Electrical wiring is the most important market for the copper industry. This includes building wire, communications cable, power distribution cable, appliance wire, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, solderability, and ease of installation.
What is the most important market for copper today?

ANS: Electrical wiring


Another common application is the control of the throttle of an internal combustion engine in conjunction with an electronic governor. In this usage, the motor works against a return spring to move the throttle in accordance with the output of the governor. The latter monitors engine speed by counting electrical pulses from the ignition system or from a magnetic pickup and, depending on the speed, makes small adjustments to the amount of current applied to the motor. If the engine starts to slow down relative to the desired speed, the current will be increased, the motor will develop more torque, pulling against the return spring and opening the throttle. Should the engine run too fast, the governor will reduce the current being applied to the motor, causing the return spring to pull back and close the throttle.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What element of a combustion engine does a governor monitor?
Ah, so.. electrical pulses


Question: Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, and nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Avivores are animals that are specialized at preying on birds.
Try to answer this question if possible: What type of birds generally feed by fishing, plant eating or piracy?
Answer: Aquatic birds


Input: Read this: The departures of Núñez and van Gaal were hardly noticed by the fans when compared to that of Luís Figo, then club vice-captain. Figo had become a cult hero, and was considered by Catalans to be one of their own. However, Barcelona fans were distraught by Figo's decision to join arch-rivals Real Madrid, and, during subsequent visits to the Camp Nou, Figo was given an extremely hostile reception. Upon his first return, a piglet's head and a full bottle of whiskey were thrown at him from the crowd. The next three years saw the club in decline, and managers came and went. van Gaal was replaced by Llorenç Serra Ferrer who, despite an extensive investment in players in the summer of 2000, presided over a mediocre league campaign and a humiliating first-round Champions League exit, and was eventually dismissed late in the season. Long-serving coach Carles Rexach was appointed as his replacement, initially on a temporary basis, and managed to at least steer the club to the last Champions League spot on the final day of the season. Despite better form in La Liga and a good run to the semi-finals of the Champions League, Rexach was never viewed as a long-term solution and that summer Louis van Gaal returned to the club for a second spell as manager. What followed, despite another decent Champions League performance, was one of the worst La Liga campaigns in the club's history, with the team as low as 15th in February 2003. This led to van Gaal's resignation and replacement for the rest of the campaign by Radomir Antić, though a sixth-place finish was the best that he could manage. At the end of the season, Antić's short-term contract was not renewed, and club president Joan Gaspart resigned, his position having been made completely untenable by such a disastrous season on top of the club's overall decline in fortunes since he became president three years prior.
Question: What rank was club Barcelona in 2003?

Output:
15th
