Problem: Hunter-gatherers tend to have an egalitarian social ethos, although settled hunter-gatherers (for example, those inhabiting the Northwest Coast of North America) are an exception to this rule. Nearly all African hunter-gatherers are egalitarian, with women roughly as influential and powerful as men.
 Where do people who are an exception to egalitarianism live?
The answer is the following: Northwest Coast of North America

Problem: The Soviet Union also fixed the parachute and control problems with Soyuz, and the next piloted mission Soyuz 3 was launched on October 26, 1968. The goal was to complete Komarov's rendezvous and docking mission with the un-piloted Soyuz 2. Ground controllers brought the two craft to within 200 meters (660 ft) of each other, then cosmonaut Georgy Beregovoy took control. He got within 40 meters (130 ft) of his target, but was unable to dock before expending 90 percent of his maneuvering fuel, due to a piloting error that put his spacecraft into the wrong orientation and forced Soyuz 2 to automatically turn away from his approaching craft. The first docking of Soviet spacecraft was finally realised in January 1969 by the Soyuz 4 and Soyuz 5 missions. It was the first-ever docking of two manned spacecraft, and the first transfer of crew from one space vehicle to another.
When was the first successful docking of a two man space crew?
The answer is the following: January 1969

Problem: Chopin's polonaises show a marked advance on those of his Polish predecessors in the form (who included his teachers Zywny and Elsner). As with the traditional polonaise, Chopin's works are in triple time and typically display a martial rhythm in their melodies, accompaniments and cadences. Unlike most of their precursors, they also require a formidable playing technique.
What time are Chopin's polonaises written in?
The answer is the following: triple time

Problem: By 287 BC, the economic condition of the average plebeian had become poor. The problem appears to have centered around widespread indebtedness. The plebeians demanded relief, but the senators refused to address their situation. The result was the final plebeian secession. The plebeians seceded to the Janiculum hill. To end the secession, a dictator was appointed. The dictator passed a law (the Lex Hortensia), which ended the requirement that the patrician senators must agree before any bill could be considered by the Plebeian Council. This was not the first law to require that an act of the Plebeian Council have the full force of law. The Plebeian Council acquired this power during a modification to the original Valerian law in 449 BC. The significance of this law was in the fact that it robbed the patricians of their final weapon over the plebeians. The result was that control over the state fell, not onto the shoulders of voters, but to the new plebeian nobility.
What law was passed that allowed the Plebeian Council to consider a bill without the approval of the patrician senators?
The answer is the following:
the Lex Hortensia
