[Q]: Extract the answer to the question from the following context. Question: Usually, what can't use these elegators? Context: A freight elevator, or goods lift, is an elevator designed to carry goods, rather than passengers. Freight elevators are generally required to display a written notice in the car that the use by passengers is prohibited (though not necessarily illegal), though certain freight elevators allow dual use through the use of an inconspicuous riser. In order for an elevator to be legal to carry passengers in some jurisdictions it must have a solid inner door. Freight elevators are typically larger and capable of carrying heavier loads than a passenger elevator, generally from 2,300 to 4,500 kg. Freight elevators may have manually operated doors, and often have rugged interior finishes to prevent damage while loading and unloading. Although hydraulic freight elevators exist, electric elevators are more energy efficient for the work of freight lifting.[citation needed]

input: Please answer the following: Extract the answer to the question from the following context. Question: How do we know anything about Dominic? Context: Dominic's search for a close relationship with God was determined and unceasing. He rarely spoke, so little of his interior life is known. What is known about it comes from accounts written by people near to him. St. Cecilia remembered him as cheerful, charitable and full of unceasing vigor. From a number of accounts, singing was apparently one of Dominic's great delights. Dominic practiced self-scourging and would mortify himself as he prayed alone in the chapel at night for 'poor sinners.' He owned a single habit, refused to carry money, and would allow no one to serve him.

Please answer this: Extract the answer to the question from the following context. Question: What mind altering plant could you have and not get into as much trouble as before? Context: Left-wing politics have been particularly strong in municipal government since the 1960s. Voters approved charter amendments that have lessened the penalties for possession of marijuana (1974), and that aim to protect access to abortion in the city should it ever become illegal in the State of Michigan (1990). In 1974, Kathy Kozachenko's victory in an Ann Arbor city-council race made her the country's first openly homosexual candidate to win public office. In 1975, Ann Arbor became the first U.S. city to use instant-runoff voting for a mayoral race. Adopted through a ballot initiative sponsored by the local Human Rights Party, which feared a splintering of the liberal vote, the process was repealed in 1976 after use in only one election. As of August 2009, Democrats hold the mayorship and all council seats. The left tilt of politics in the city has earned it the nickname "The People's Republic of Ann Arbor". Nationally, Ann Arbor is located in Michigan's 12th congressional district, represented by Democrat Debbie Dingell.

Problem: Extract the answer to the question from the following context. Question: What religious part do youth become responsible for by the end of adolescence? Context: Adolescence is frequently characterized by a transformation of an adolescent's understanding of the world, the rational direction towards a life course, and the active seeking of new ideas rather than the unquestioning acceptance of adult authority. An adolescent begins to develop a unique belief system through his or her interaction with social, familial, and cultural environments. While organized religion is not necessarily a part of every adolescent's life experience, youth are still held responsible for forming a set of beliefs about themselves, the world around them, and whatever higher powers they may or may not believe in. This process is often accompanied or aided by cultural traditions that intend to provide a meaningful transition to adulthood through a ceremony, ritual, confirmation, or rite of passage.

A: whatever higher powers they may or may not believe in

Problem: Given the question: Extract the answer to the question from the following context. Question: What did Hitler hope the Blitz would accomplish? Context: The bombing failed to demoralise the British into surrender or significantly damage the war economy. The eight months of bombing never seriously hampered British production and the war industries continued to operate and expand. The Blitz was only authorised when the Luftwaffe had failed to meet preconditions for a 1940 launch of Operation Sea Lion, the provisionally planned German invasion of Britain. By May 1941 the threat of an invasion of Britain had passed, and Hitler's attention had turned to Operation Barbarossa in the East. In comparison to the later Allied bombing campaign against Germany, the Blitz resulted in relatively few casualties; the British bombing of Hamburg in July 1943 inflicted some 42,000 civilian deaths, about the same as the entire Blitz.

Problem: Extract the answer to the question from the following context. Question: What method pioneered the movement forward for sound systems? Context: The development of quadraphonic records was announced in 1971. These recorded four separate sound signals. This was achieved on the two stereo channels by electronic matrixing, where the additional channels were combined into the main signal. When the records were played, phase-detection circuits in the amplifiers were able to decode the signals into four separate channels. There were two main systems of matrixed quadraphonic records produced, confusingly named SQ (by CBS) and QS (by Sansui). They proved commercially unsuccessful, but were an important precursor to later surround-sound systems, as seen in SACD and home cinema today.

A:
This was achieved on the two stereo channels by electronic matrixing, where the additional channels were combined into the main signal
