Article: Northwestern's football team has made 73 appearances in the top 10 of the AP poll since 1936 (including 5 at #1) and has won eight Big Ten conference championships since 1903. At one time, Northwestern had the longest losing streak in Division I-A, losing 34 consecutive games between 1979 and 1982. They did not appear in a bowl game after 1949 until the 1996 Rose Bowl. The team did not win a bowl since the 1949 Rose Bowl until the 2013 Gator Bowl. Following the sudden death of football coach Randy Walker in 2006, 31-year-old former All-American Northwestern linebacker Pat Fitzgerald assumed the position, becoming the youngest Division I FBS coach at the time.

Question: How many consecutive games did Northwestern lose during it's longest losing streak between 1979 and 1982?
Ans: 34

Article: Albert Einstein is known for his theories of special relativity and general relativity. He also made important contributions to statistical mechanics, especially his mathematical treatment of Brownian motion, his resolution of the paradox of specific heats, and his connection of fluctuations and dissipation. Despite his reservations about its interpretation, Einstein also made contributions to quantum mechanics and, indirectly, quantum field theory, primarily through his theoretical studies of the photon.

Question: What is Albert Einstein known for?
Ans: his theories of special relativity and general relativity

Article: Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength.

Question: What mostly affects polarization?
Ans: Reflections

Article: In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of Western European feudalism. Nevertheless, urban merchants, artisans and labourers sometimes exercised political influence through a city assembly, the veche (council), which included all the adult males in the population. In some cases, the veche either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a stratum of slaves. More important was a class of tribute-paying peasants, who owed labour duty to the princes. The widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus'.

Question: What was the group called that owed labour duty to the princes?
Ans:
tribute-paying peasants
