Problem: Black people:

Scholars disagree over the effects of social status on racial classifications in Brazil. It is generally believed that achieving upward mobility and education results in individuals being classified as a category of lighter skin. The popular claim is that in Brazil, poor whites are considered black and wealthy blacks are considered white. Some scholars disagree, arguing that "whitening" of one's social status may be open to people of mixed race, a large part of the population known as pardo, but a person perceived as preto (black) will continue to be classified as black regardless of wealth or social status.

What type of skin color has a better chance of a good life in Brazil?
---
A: lighter skin

Problem: Russian Soviet Federative Socialist Republic:

On December 8, 1991, at Viskuli near Brest (Belarus), the President of the Russian SFSR and the heads of Byelorussian SSR and Ukrainian SSR signed the "Agreement on the Establishment of the Commonwealth of Independent States" (known in media as Belavezha Accords). The document, consisting of a preamble and fourteen articles, stated that the Soviet Union ceased to exist as a subject of international law and geopolitical reality. However, based on the historical community of peoples, relations between them, given the bilateral treaties, the desire for a democratic rule of law, the intention to develop their relations based on mutual recognition and respect for state sovereignty, the parties agreed to the formation of the Commonwealth of Independent States. On December 12, the agreement was ratified by the Supreme Soviet of the Russian SFSR by an overwhelming majority: 188 votes for, 6 against, 7 abstentions. On the same day, the Supreme Soviet of the Russian SFSR denounced the Treaty on the Creation of the USSR and recalled all Russian deputies from the Supreme Soviet of the Soviet Union. The legality of this act is the subject of discussions because, according to the 1978 Constitution (Basic Law) of the Russian SFSR, the Russian Supreme Soviet had no right to do so. However, by this time the Soviet government had been rendered more or less impotent, and was in no position to object. Although the December 12 vote is sometimes reckoned as the moment that the RSFSR seceded from the collapsing Soviet Union, this is not the case. It appears that the RSFSR took the line that it was not possible to secede from an entity that no longer existed.

On what date was the Agreement on the Establishment of the Commonwealth of Independent States signed?
---
A: December 8, 1991

Problem: Roman Republic:

In 118 BC, King Micipsa of Numidia (current-day Algeria and Tunisia) died. He was succeeded by two legitimate sons, Adherbal and Hiempsal, and an illegitimate son, Jugurtha. Micipsa divided his kingdom between these three sons. Jugurtha, however, turned on his brothers, killing Hiempsal and driving Adherbal out of Numidia. Adherbal fled to Rome for assistance, and initially Rome mediated a division of the country between the two brothers. Eventually, Jugurtha renewed his offensive, leading to a long and inconclusive war with Rome. He also bribed several Roman commanders, and at least two tribunes, before and during the war. His nemesis, Gaius Marius, a legate from a virtually unknown provincial family, returned from the war in Numidia and was elected consul in 107 BC over the objections of the aristocratic senators. Marius invaded Numidia and brought the war to a quick end, capturing Jugurtha in the process. The apparent incompetence of the Senate, and the brilliance of Marius, had been put on full display. The populares party took full advantage of this opportunity by allying itself with Marius.

Which individual did the populares part have an allegiance with?
---
A: Marius

Problem: Guam:

Post-European-contact Chamorro culture is a combination of American, Spanish, Filipino, other Micronesian Islander and Mexican traditions, with few remaining indigenous pre-Hispanic customs. These influences are manifested in the local language, music, dance, sea navigation, cuisine, fishing, games (such as batu, chonka, estuleks, and bayogu), songs and fashion. During Spanish colonial rule (16681898) the majority of the population was converted to Roman Catholicism and religious festivities such as Easter and Christmas became widespread. Post-contact Chamorro cuisine is largely based on corn, and includes tortillas, tamales, atole and chilaquiles, which are a clear influence from Spanish trade between Mesoamerica and Asia. The modern Chamorro language is a Malayo-Polynesian language with much Spanish and Filipino influence. Many Chamorros also have Spanish surnames because of their conversion to Roman Catholic Christianity and the adoption of names from the Catalogo alfabetico de apellidos, a phenomenon also common to the Philippines.

In what year was the catalogo alfabetico de apellidos published?
