The prohibition question is a tricky one. The 18th amendment was ratified in 1919, but Wikipedia says "By the terms of the amendment, the country went dry one year later, on January 17, 1920" and everything said early 1920 when I looked it up.
Eistein published the Special Relativity Theory in 1905. The General Relativity Theory was published in 1916. It would be more correct to let the possibility be "The general relativity theory" and not just "the raltivity theory".
Other than that, great quiz!
