Problem:Context: Michael Collins (born October 31, 1930) (Major General, USAF, Ret.) is an American former astronaut and test pilot. Selected as part of the third group of fourteen astronauts in 1963, he flew into space twice. His first spaceflight was on Gemini 10, in which he and Command Pilot John Young performed two rendezvous with different spacecraft and undertook two extra-vehicular activities (EVAs, also known as spacewalks). His second spaceflight was as the Command Module Pilot for Apollo 11. While he stayed in orbit around the Moon, Neil Armstrong and Buzz Aldrin left in the Lunar Module to make the first manned landing on its surface. He is one of 24 people to have flown to the Moon.

Question: who was the only member of the apollo 11 moon expedition who did not walk on the moon?
Solution:OK... To answer this question, we should know that: While he stayed in orbit around the Moon, Neil Armstrong and Buzz Aldrin left in the Lunar Module to make the first manned landing on its surface.
Michael Collins.

Student A:As in many industrialised countries, nuclear power in Germany was first developed in the late 1950s. Only a few experimental reactors went online before 1960, and an experimental nuclear power station in Kahl am Main opened in 1960. All of the German nuclear power plants that opened between 1960 and 1970 had a power output of less than 1,000 MW and have now all closed down. The first commercial nuclear power plant started operating in 1969. Obrigheim, the first grid station, operated until 2005. (Neckarwestheim.) A closed nuclear fuel cycle was planned, starting with mining operations in the Saarland and the Schwarzwald; uranium ore concentration, fuel rod filling production in Hanau; and reprocessing of the spent fuel in the never-built nuclear fuel reprocessing plant at Wackersdorf. The radioactive waste was intended to be stored in a deep geological repository, as part of the Gorleben long-term storage project.

When did germany build its first nuclear power plant?
Student B:OK... The relevant information to answer the above question is: Only a few experimental reactors went online before 1960, and an experimental nuclear power station in Kahl am Main opened in 1960.
1960.

Problem:In measurements of purely mechanical systems (involving units of length, mass, force, energy, pressure, and so on), the differences between CGS and SI are straightforward and rather trivial; the unit-conversion factors are all powers of 10 as 100 cm = 1 m and 1000 g = 1 kg. For example, the CGS unit of force is the dyne which is defined as 1 g ⋅ cm / s, so the SI unit of force, the newton (1 kg ⋅ m / s), is equal to 100,000 dynes.

The unit of force in cgs unit is?
Solution:OK... To answer the question, consider the following: For example, the CGS unit of force is the dyne which is defined as 1 g ⋅ cm / s, so the SI unit of force, the newton (1 kg ⋅ m / s), is equal to 100,000 dynes.
dyne.

Student A:Context: Daylight saving time in the United States is the practice of setting the clock forward by one hour during the warmer part of the year, so that evenings have more daylight and mornings have less. Most areas of the United States observe daylight saving time (DST), the exceptions being Arizona (except for the Navajo, who do observe daylight saving time on tribal lands), Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Uniform Time Act of 1966 established the system of uniform Daylight Saving Time throughout the US.

Question: states that do not have daylight saving time?
Student B:OK... To answer this question, we should know that: Most areas of the United States observe daylight saving time (DST), the exceptions being Arizona (except for the Navajo, who do observe daylight saving time on tribal lands), Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands.
Arizona ( except for the Navajo , who do observe daylight saving time on tribal lands ) , Hawaii.

Problem:William McKinley (January 29, 1843 -- September 14, 1901) was the 25th President of the United States, serving from March 4, 1897 until his assassination in September 1901, six months into his second term. McKinley led the nation to victory in the Spanish -- American War, raised protective tariffs to promote American industry, and maintained the nation on the gold standard in a rejection of free silver (effectively, expansionary monetary policy).

Answer this question based on the passage: who was the president of the united states in 1900?
Solution:OK... To answer the above question, the relevant sentence is: William McKinley (January 29, 1843 -- September 14, 1901) was the 25th President of the United States, serving from March 4, 1897 until his assassination in September 1901, six months into his second term.
William McKinley.

Problem:Bristol Motor Speedway, formerly known as Bristol International Raceway and Bristol Raceway, is a NASCAR short track venue located in Bristol, Tennessee. Constructed in 1960, it held its first NASCAR race on July 30, 1961. Despite its short length, Bristol is among the most popular tracks on the NASCAR schedule because of its distinct features, which include extraordinarily steep banking, an all concrete surface, two pit roads, and stadium-like seating. It has also been named one of the loudest NASCAR tracks.

Based on this passage, is bristol motor speedway in tennessee or virginia?
Solution:
OK... The relevant information to answer the above question is: Bristol Motor Speedway, formerly known as Bristol International Raceway and Bristol Raceway, is a NASCAR short track venue located in Bristol, Tennessee.
Tennessee.
