Problem: Please answer a question about the following article about Indigenous peoples of the Americas:
The music of the indigenous peoples of Central Mexico and Central America was often pentatonic. Before the arrival of the Spaniards and other Europeans, music was inseparable from religious festivities and included a large variety of percussion and wind instruments such as drums, flutes, sea snail shells (used as a trumpet) and "rain" tubes. No remnants of pre-Columbian stringed instruments were found until archaeologists discovered a jar in Guatemala, attributed to the Maya of the Late Classic Era (600900 CE), which depicts a stringed musical instrument which has since been reproduced. This instrument is one of the very few stringed instruments known in the Americas prior to the introduction of European musical instruments; when played it produces a sound virtually identical to a jaguar's growl.
What feature did the music of Central America have?
A: pentatonic
Problem: Please answer a question about the following article about Mexico City:
Even though proportionality is confined to the proportional seats to prevent a part from being overrepresented, several restrictions apply in the assignation of the seats; namely, that no party can have more than 63% of all seats, both uninominal and plurinominal. In the 2006 elections leftist PRD got the absolute majority in the direct uninominal elections, securing 34 of the 40 FPP seats. As such, the PRD was not assigned any plurinominal seat to comply with the law that prevents over-representation. The overall composition of the Legislative Assembly is:
What is the maximum percentage of seats a single party can control?
A: 63
Problem: Please answer a question about the following article about Raleigh, North Carolina:
The National Hockey League's Carolina Hurricanes franchise moved to Raleigh in 1997 from Hartford, Connecticut (where it was known as the Hartford Whalers). The team played its first two seasons more than 60 miles away at Greensboro Coliseum while its home arena, Raleigh Entertainment and Sports Arena (later RBC Center and now PNC Arena), was under construction. The Hurricanes are the only major league (NFL, NHL, NBA, MLB) professional sports team in North Carolina to have won a championship, winning the Stanley Cup in 2006, over the Edmonton Oilers. The city played host to the 2011 NHL All-Star Game.
What is the home stadium of the Carolina Hurricanes called?
A: PNC Arena
Problem: Please answer a question about the following article about Group (mathematics):
In abstract algebra, more general structures are defined by relaxing some of the axioms defining a group. For example, if the requirement that every element has an inverse is eliminated, the resulting algebraic structure is called a monoid. The natural numbers N (including 0) under addition form a monoid, as do the nonzero integers under multiplication (Z {0}, ), see above. There is a general method to formally add inverses to elements to any (abelian) monoid, much the same way as (Q {0}, ) is derived from (Z {0}, ), known as the Grothendieck group. Groupoids are similar to groups except that the composition a b need not be defined for all a and b. They arise in the study of more complicated forms of symmetry, often in topological and analytical structures, such as the fundamental groupoid or stacks. Finally, it is possible to generalize any of these concepts by replacing the binary operation with an arbitrary n-ary one (i.e. an operation taking n arguments). With the proper generalization of the group axioms this gives rise to an n-ary group. The table gives a list of several structures generalizing groups.
What product is created if the requirement that every element has an inverse is eliminated?
A:
monoid
