PROBLEM: Which of these Greeks knows more about physics: Joseph Sifakis or John Iliopoulos?, Context: As of 2007, Greece had the eighth highest percentage of tertiary enrollment in the world (with the percentages for female students being higher than for male) while Greeks of the Diaspora are equally active in the field of education. Hundreds of thousands of Greek students attend western universities every year while the faculty lists of leading Western universities contain a striking number of Greek names. Notable modern Greek scientists of modern times include Dimitrios Galanos, Georgios Papanikolaou (inventor of the Pap test), Nicholas Negroponte, Constantin Caratheodory, Manolis Andronikos, Michael Dertouzos, John Argyris, Panagiotis Kondylis, John Iliopoulos (2007 Dirac Prize for his contributions on the physics of the charm quark, a major contribution to the birth of the Standard Model, the modern theory of Elementary Particles), Joseph Sifakis (2007 Turing Award, the "Nobel Prize" of Computer Science), Christos Papadimitriou (2002 Knuth Prize, 2012 Godel Prize), Mihalis Yannakakis (2005 Knuth Prize) and Dimitri Nanopoulos.

PROBLEM: Which happened earlier, the defeat of the Confederacy or the founding of the Red Shirts?, Context: With the defeat of the Confederacy in 1865, the Reconstruction Era began. The United States abolished slavery without compensation to slaveholders or reparations to freedmen. A Republican Party coalition of black freedmen, northern carpetbaggers and local scalawags controlled state government for three years. The white conservative Democrats regained control of the state legislature in 1870, in part by Ku Klux Klan violence and terrorism at the polls, to suppress black voting. Republicans were elected to the governorship until 1876, when the Red Shirts, a paramilitary organization that arose in 1874 and was allied with the Democratic Party, helped suppress black voting. More than 150 black Americans were murdered in electoral violence in 1876.

SOLUTION:
the defeat of the Confederacy
