Problem: Police:

In France during the Middle Ages, there were two Great Officers of the Crown of France with police responsibilities: The Marshal of France and the Constable of France. The military policing responsibilities of the Marshal of France were delegated to the Marshal's provost, whose force was known as the Marshalcy because its authority ultimately derived from the Marshal. The marshalcy dates back to the Hundred Years' 'War, and some historians trace it back to the early 12th century. Another organisation, the Constabulary (French: Connetablie), was under the command of the Constable of France. The constabulary was regularised as a military body in 1337. Under King Francis I (who reigned 15151547), the Marechaussee was merged with the Constabulary. The resulting force was also known as the Marechaussee, or, formally, the Constabulary and Marshalcy of France.

Problem: Frederic Chopin:

Chopin took the new salon genre of the nocturne, invented by the Irish composer John Field, to a deeper level of sophistication. He was the first to write ballades and scherzi as individual concert pieces. He essentially established a new genre with his own set of free-standing preludes (Op. 28, published 1839). He exploited the poetic potential of the concept of the concert etude, already being developed in the 1820s and 1830s by Liszt, Clementi and Moscheles, in his two sets of studies (Op. 10 published in 1833, Op. 25 in 1837).

What musical concept did Chopin exploit?
---
A: concert etude

Problem: To Kill a Mockingbird:

Atticus does not want Jem and Scout to be present at Tom Robinson's trial. No seat is available on the main floor, so by invitation of Rev. Sykes, Jem, Scout, and Dill watch from the colored balcony. Atticus establishes that the accusersMayella and her father, Bob Ewell, the town drunkare lying. It also becomes clear that the friendless Mayella made sexual advances toward Tom, and that her father caught her and beat her. Despite significant evidence of Tom's innocence, the jury convicts him. Jem's faith in justice becomes badly shaken, as is Atticus', when the hapless Tom is shot and killed while trying to escape from prison.
