input: Please answer the following: Extract the answer to the question from the following context. Question: Children that are mixed-race are given social status by which tribe? Context: The social identity of the children was strongly determined by the tribe's kinship system. Among the matrilineal tribes of the Southeast, the mixed-race children generally were accepted as and identified as Indian, as they gained their social status from their mother's clans and tribes, and often grew up with their mothers and their male relatives. By contrast, among the patrilineal Omaha, for example, the child of a white man and Omaha woman was considered "white"; such mixed-race children and their mothers would be protected, but the children could formally belong to the tribe as members only if adopted by a man.

output: matrilineal tribes of the Southeast

Please answer this: Extract the answer to the question from the following context. Question: What was once scarce or non-existent in the US before intervention? Context: It has been possible to teach a migration route to a flock of birds, for example in re-introduction schemes. After a trial with Canada geese Branta canadensis, microlight aircraft were used in the US to teach safe migration routes to reintroduced whooping cranes Grus americana.

Problem: Extract the answer to the question from the following context. Question: Which are there more of: preliminary routines or points in the maximum score? Context: Individual routines in trampolining involve a build-up phase during which the gymnast jumps repeatedly to achieve height, followed by a sequence of ten bounces without pause during which the gymnast performs a sequence of aerial skills. Routines are marked out of a maximum score of 10 points. Additional points (with no maximum at the highest levels of competition) can be earned depending on the difficulty of the moves and the length of time taken to complete the ten skills which is an indication of the average height of the jumps. In high level competitions, there are two preliminary routines, one which has only two moves scored for difficulty and one where the athlete is free to perform any routine. This is followed by a final routine which is optional. Some competitions restart the score from zero for the finals, other add the final score to the preliminary results.

A: points

Problem: Given the question: Extract the answer to the question from the following context. Question: Which of the following people did not take a course at the LSA summer institute: Alan Prince, John McCarthy or Paul Smolensky? Context: In a course at the LSA summer institute in 1991, Alan Prince and Paul Smolensky developed optimality theoryan overall architecture for phonology according to which languages choose a pronunciation of a word that best satisfies a list of constraints ordered by importance; a lower-ranked constraint can be violated when the violation is necessary in order to obey a higher-ranked constraint. The approach was soon extended to morphology by John McCarthy and Alan Prince, and has become a dominant trend in phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) in various approaches has been criticized by proponents of 'substance-free phonology', especially Mark Hale and Charles Reiss.

The answer is:
John McCarthy

output answer: nation with the most elevators installed in the world

input question: Extract the answer to the question from the following context. Question: Which of the following is not a characteristic of intermetallic compounds: defined stoichiometry, bond types, or crystal structure? Context: An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by metallic bonding character. An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure. Zintl phases are also sometimes considered alloys depending on bond types (see also: Van Arkel-Ketelaar triangle for information on classifying bonding in binary compounds).???
output answer:
bond types
