Input: Read this: The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11 percent of the surface area of Europe, the Alps provide up to 90 percent of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80 percent of water from Alpine runoff. Water from the rivers is used in over 500 hydroelectricity power plants, generating as much as 2900 kilowatts of electricity.
Question: Water from the rivers is used in over how many hydroelectric power plants?

Output: 500

QUES: Smaller boats and ships typically have machine-guns or fast cannons, which can often be deadly to low-flying aircraft if linked to a radar-directed fire-control system radar-controlled cannon for point defence. Some vessels like Aegis cruisers are as much a threat to aircraft as any land-based air defence system. In general, naval vessels should be treated with respect by aircraft, however the reverse is equally true. Carrier battle groups are especially well defended, as not only do they typically consist of many vessels with heavy air defence armament but they are also able to launch fighter jets for combat air patrol overhead to intercept incoming airborne threats.

These weapons can be deadly to aircraft that is low if it is linked to what?
What is the answer?
ANS: a radar-directed fire-control system radar-controlled cannon for point defence

QUES: At June 1985's Consumer Electronics Show (CES), Nintendo unveiled the American version of its Famicom. This is the system which would eventually be officially deployed as the Nintendo Entertainment System, or the colloquial "NES". Nintendo seeded these first systems to limited American test markets starting in New York City on October 18, 1985, following up with a full-fledged North American release of the console in February of the following year. Nintendo released 17 launch titles: 10-Yard Fight, Baseball, Clu Clu Land, Duck Hunt, Excitebike, Golf, Gyromite, Hogan's Alley, Ice Climber, Kung Fu, Pinball, Soccer, Stack-Up, Tennis, Wild Gunman, Wrecking Crew, and Super Mario Bros.h["] Some varieties of these launch games contained Famicom chips with an adapter inside the cartridge so they would play on North American consoles, which is why the title screen of Gyromite has the Famicom title "Robot Gyro" and the title screen of Stack-Up has the Famicom title "Robot Block".
What was the abbreviation for Nintendo NonEntertainment System?

Beer ranges from less than 3% alcohol by volume (abv) to around 14% abv, though this strength can be increased to around 20% by re-pitching with champagne yeast, and to 55% abv by the freeze-distilling process. The alcohol content of beer varies by local practice or beer style. The pale lagers that most consumers are familiar with fall in the range of 46%, with a typical abv of 5%. The customary strength of British ales is quite low, with many session beers being around 4% abv. Some beers, such as table beer are of such low alcohol content (1%4%) that they are served instead of soft drinks in some schools.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where are British ales served instead of soft drinks?
Ah, so.. unanswerable

Question: Backup and Restore, the backup component of Windows, is deprecated.
