Input: Buddhism
The concept of liberation (nirvāṇa)—the goal of the Buddhist path—is closely related to overcoming ignorance (avidyā), a fundamental misunderstanding or mis-perception of the nature of reality. In awakening to the true nature of the self and all phenomena one develops dispassion for the objects of clinging, and is liberated from suffering (dukkha) and the cycle of incessant rebirths (saṃsāra). To this end, the Buddha recommended viewing things as characterized by the three marks of existence.

Buddha recommended viewing thing by how many marks of existence?
Output: three

Input: Computer
The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.

What was Kilby's IC made of?
Output: germanium

Input: Solar energy
Pumped-storage hydroelectricity stores energy in the form of water pumped when energy is available from a lower elevation reservoir to a higher elevation one. The energy is recovered when demand is high by releasing the water, with the pump becoming a hydroelectric power generator.

How is the energy stored by pumped-storage hydroelectricity recovered?
Output: by releasing the water, with the pump becoming a hydroelectric power generator

Input: Montana
There are at least 3,223 named lakes and reservoirs in Montana, including Flathead Lake, the largest natural freshwater lake in the western United States. Other major lakes include Whitefish Lake in the Flathead Valley and Lake McDonald and St. Mary Lake in Glacier National Park. The largest reservoir in the state is Fort Peck Reservoir on the Missouri river, which is contained by the second largest earthen dam and largest hydraulically filled dam in the world. Other major reservoirs include Hungry Horse on the Flathead River; Lake Koocanusa on the Kootenai River; Lake Elwell on the Marias River; Clark Canyon on the Beaverhead River; Yellowtail on the Bighorn River, Canyon Ferry, Hauser, Holter, Rainbow; and Black Eagle on the Missouri River.

What is the name of the largest freshwater lake in western United States?
Output:
Flathead Lake
