Problem: Chicago Cubs:

The "Bleacher Bums" is a name given to fans, many of whom spend much of the day heckling, who sit in the bleacher section at Wrigley Field. Initially, the group was called "bums" because it referred to a group of fans who were at most games, and since those games were all day games, it was assumed they did not work. Many of those fans were, and are still, students at Chicago area colleges, such as DePaul University, Loyola, Northwestern University, and Illinois-Chicago. A Broadway play, starring Joe Mantegna, Dennis Farina, Dennis Franz, and James Belushi ran for years and was based on a group of Cub fans who frequented the club's games. The group was started in 1967 by dedicated fans Ron Grousl, Tom Nall and "mad bugler" Mike Murphy, who was a sports radio host during mid days on Chicago-based WSCR AM 670 "The Score". Murphy alleges that Grousl started the Wrigley tradition of throwing back opposing teams' home run balls. The current group is headed by Derek Schaul (Derek the Five Dollar Kid). Prior to the 2006 season, they were updated, with new shops and private bar (The Batter's Eye) being added, and Bud Light bought naming rights to the bleacher section, dubbing them the Bud Light Bleachers. Bleachers at Wrigley are general admission, except during the playoffs. The bleachers have been referred to as the "World's Largest Beer Garden." A popular T-shirt (sold inside the park and licensed by the club) which says "Wrigley Bleachers" on the front and the phrase "Shut Up and Drink Your Beer" on the reverse fuels this stereotype.

Who heads the current group?

A: Derek Schaul

Problem: Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolutionit is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype.

Philip II of Spain decreed the change from the Julian to the Gregorian calendar, which affected much of Roman Catholic Europe, as Philip was at the time ruler over Spain and Portugal as well as much of Italy. In these territories, as well as in the PolishLithuanian Commonwealth (ruled by Anna Jagiellon) and in the Papal States, the new calendar was implemented on the date specified by the bull, with Julian Thursday, 4 October 1582, being followed by Gregorian Friday, 15 October 1582. The Spanish and Portuguese colonies followed somewhat later de facto because of delay in communication.
What ruler decreed the change to the Gregorian calendar?
A: Philip II of Spain

Context and question: The Soviet Union, which feared Western powers and the possibility of "capitalist encirclements", had little faith either that war could be avoided, or faith in the Polish army, and wanted nothing less than an ironclad military alliance with France and Britain that would provide a guaranteed support for a two-pronged attack on Germany; thus, Stalin's adherence to the collective security line was purely conditional. Britain and France believed that war could still be avoided, and that the Soviet Union, weakened by the Great Purge, could not be a main military participant, a point that many military sources were at variance with, especially Soviet victories over the Japanese Kwantung army on the Manchurian frontier. France was more anxious to find an agreement with the USSR than was Britain; as a continental power, it was more willing to make concessions, more fearful of the dangers of an agreement between the USSR and Germany. These contrasting attitudes partly explain why the USSR has often been charged with playing a double game in 1939: carrying on open negotiations for an alliance with Britain and France while secretly considering propositions from Germany.
What country was at war with Japan in China prior to World War II?
Answer: Soviet Union

Question: In 200607, researchers from the Wildlife Conservation Society studied gorillas in heavily forested regions centered on the Ouesso district of the Sangha Region. They suggest a population on the order of 125,000 Western Lowland Gorillas, whose isolation from humans has been largely preserved by inhospitable swamps.
Is there an answer to this question: When did researchers from the Wildlife Conservation Society study chimps?

Answer: unanswerable

New York City also has an extensive web of expressways and parkways, which link the city's boroughs to each other as well as to northern New Jersey, Westchester County, Long Island, and southwestern Connecticut through various bridges and tunnels. Because these highways serve millions of outer borough and suburban residents who commute into Manhattan, it is quite common for motorists to be stranded for hours in traffic jams that are a daily occurrence, particularly during rush hour.
What part of New Jersey can be reached from New York by taking the expressway?
A:
northern
