Problem: Friedrich Hayek:

Hayek had a long-standing and close friendship with philosopher of science Karl Popper, also from Vienna. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." (See Hacohen, 2000). Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper and, in 1982, said that "ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology". Popper also participated in the inaugural meeting of the Mont Pelerin Society. Their friendship and mutual admiration, however, do not change the fact that there are important differences between their ideas.

Who is the only exception from whom Hayek claims to have learned more than he did from Popper?

A: Alfred Tarski


Problem: Compact disc:

Compact Disc + Graphics is a special audio compact disc that contains graphics data in addition to the audio data on the disc. The disc can be played on a regular audio CD player, but when played on a special CD+G player, it can output a graphics signal (typically, the CD+G player is hooked up to a television set or a computer monitor); these graphics are almost exclusively used to display lyrics on a television set for karaoke performers to sing along with. The CD+G format takes advantage of the channels R through W. These six bits store the graphics information.

How many bits does a normal CD use?
---
A: unanswerable


Problem: The Bronx:

The Bronx's evolution from a hot bed of Latin jazz to an incubator of hip hop was the subject of an award-winning documentary, produced by City Lore and broadcast on PBS in 2006, "From Mambo to Hip Hop: A South Bronx Tale". Hip Hop first emerged in the South Bronx in the early 1970s. The New York Times has identified 1520 Sedgwick Avenue "an otherwise unremarkable high-rise just north of the Cross Bronx Expressway and hard along the Major Deegan Expressway" as a starting point, where DJ Kool Herc presided over parties in the community room.

What PBS documentary covered the Bronx's music history?
---
A: "From Mambo to Hip Hop: A South Bronx Tale"


Problem: Pacific War:

U.S. submarines accounted for 56% of the Japanese merchantmen sunk; mines or aircraft destroyed most of the rest. US submariners also claimed 28% of Japanese warships destroyed. Furthermore, they played important reconnaissance roles, as at the battles of the Philippine Sea (June 1944) and Leyte Gulf (October 1944) (and, coincidentally,[clarification needed] at Midway in June 1942), when they gave accurate and timely warning of the approach of the Japanese fleet. Submarines also rescued hundreds of downed fliers, including future U.S. president George H.W. Bush.

What was one of the important roles submarine played in the war?
---
A:
reconnaissance roles
