Problem: United States dollar:

In the 16th century, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English), named for Joachimstal, the valley where the silver was mined (St. Joachim's Valley, now Jachymov; then part of the Kingdom of Bohemia, now part of the Czech Republic). Joachimstaler was later shortened to the German Taler, a word that eventually found its way into Danish and Swedish as daler, Norwegian as dalar and daler, Dutch as daler or daalder, Ethiopian as (talari), Hungarian as taller, Italian as tallero, and English as dollar. Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal.

What is the modern name for St. Joachim's Valley?

A: Jachymov

Problem: Dialect:

Modern standard Italian itself is heavily based on the Latin-derived Florentine Tuscan language. The Tuscan-based language that would eventually become modern standard Italian had been used in poetry and literature since at least the 12th century, and it first became widely known in Italy through the works of authors such as Dante Alighieri, Giovanni Boccaccio, Niccolo Machiavelli, and Petrarch. Dante's Florentine-Tuscan literary Italian thus became the language of the literate and upper class in Italy, and it spread throughout the peninsula as the lingua franca among the Italian educated class as well as Italian traveling merchants. The economic prowess and cultural and artistic importance of Tuscany in the Late Middle Ages and the Renaissance further encouraged the diffusion of the Florentine-Tuscan Italian throughout Italy and among the educated and powerful, though local and regional languages remained the main languages of the common people.

From what region of Italy did Florentine Tuscan derive?
---
A: Tuscany

Problem: Capital punishment in the United States:

In a five-to-four decision, the Supreme Court struck down the impositions of the death penalty in each of the consolidated cases as unconstitutional. The five justices in the majority did not produce a common opinion or rationale for their decision, however, and agreed only on a short statement announcing the result. The narrowest opinions, those of Byron White and Potter Stewart, expressed generalized concerns about the inconsistent application of the death penalty across a variety of cases but did not exclude the possibility of a constitutional death penalty law. Stewart and William O. Douglas worried explicitly about racial discrimination in enforcement of the death penalty. Thurgood Marshall and William J. Brennan, Jr. expressed the opinion that the death penalty was proscribed absolutely by the Eighth Amendment as "cruel and unusual" punishment.

Aside from Stewart, what justice believed that the death penalty could be unconstitutional?
---
A: unanswerable
