Problem: History of science:

The earliest Greek philosophers, known as the pre-Socratics, provided competing answers to the question found in the myths of their neighbors: "How did the ordered cosmos in which we live come to be?" The pre-Socratic philosopher Thales (640-546 BC), dubbed the "father of science", was the first to postulate non-supernatural explanations for natural phenomena, for example, that land floats on water and that earthquakes are caused by the agitation of the water upon which the land floats, rather than the god Poseidon. Thales' student Pythagoras of Samos founded the Pythagorean school, which investigated mathematics for its own sake, and was the first to postulate that the Earth is spherical in shape. Leucippus (5th century BC) introduced atomism, the theory that all matter is made of indivisible, imperishable units called atoms. This was greatly expanded by his pupil Democritus.

Who was the first person to determine that the Earth is round?
---
A: Samos

Problem: Montevideo:

Uruguay's 1830s were dominated by the confrontation between Manuel Oribe and Fructuoso Rivera, the two revolutionary leaders who had fought against the Empire of Brazil under the command of Lavalleja, each of whom had become the caudillo of their respective faction. Politics were divided between Oribe's Blancos ("whites"), represented by the National Party, and Rivera's Colorados ("reds"), represented by the Colorado Party, with each party's name taken from the colour of its emblems. In 1838, Oribe was forced to resign the presidency; he established a rebel army and began a long civil war, the Guerra Grande, which lasted until 1851.

Manuel Oribe and Fructuoso Rivera fought under whose command?
---
A: Lavalleja

Problem: 51st state:

This constitution was created when the U.S. Congress directed local government to organize a constitutional convention to write the Puerto Rico Constitution in 1951. The acceptance of that constitution by Puerto Rico's electorate, the U.S. Congress, and the U.S. president occurred in 1952. In addition, the rights, privileges and immunities attendant to United States citizens are "respected in Puerto Rico to the same extent as though Puerto Rico were a state of the union" through the express extension of the Privileges and Immunities Clause of the U.S. Constitution by the U.S. Congress in 1948.

How was the Puerto Rican constitution brought about?
---
A: the U.S. Congress directed local government to organize a constitutional convention to write the Puerto Rico Constitution

Problem: Gymnastics:

According to FIG rules, only women compete in rhythmic gymnastics. This is a sport that combines elements of ballet, gymnastics, dance, and apparatus manipulation. The sport involves the performance of five separate routines with the use of five apparatus; ball, ribbon, hoop, clubs, ropeon a floor area, with a much greater emphasis on the aesthetic rather than the acrobatic. There are also group routines consisting of 5 gymnasts and 5 apparatuses of their choice. Rhythmic routines are scored out of a possible 30 points; the score for artistry (choreography and music) is averaged with the score for difficulty of the moves and then added to the score for execution.

How many points do gymnasts need to get to the second round?

A:
unanswerable
