Problem: Frederic Chopin:

The preludes, many of which are very brief (some consisting of simple statements and developments of a single theme or figure), were described by Schumann as "the beginnings of studies". Inspired by J.S. Bach's The Well-Tempered Clavier, Chopin's preludes move up the circle of fifths (rather than Bach's chromatic scale sequence) to create a prelude in each major and minor tonality. The preludes were perhaps not intended to be played as a group, and may even have been used by him and later pianists as generic preludes to others of his pieces, or even to music by other composers, as Kenneth Hamilton suggests: he has noted a recording by Ferruccio Busoni of 1922, in which the Prelude Op. 28 No. 7 is followed by the Etude Op. 10 No. 5.

Kenneth Hamilton suggests that the preludes may not have been meant as a group but rather as what?

A: generic preludes to others of his pieces

Problem: Chinese characters:

Examples are he "river", hu "lake", liu "stream", chong "riptide" (or "flush"), hua "slippery". All these characters have on the left a radical of three short strokes (), which is a reduced form of the character shui meaning "water", indicating that the character has a semantic connection with water. The right-hand side in each case is a phonetic indicator. For example, in the case of chong (Old Chinese *-lju), the phonetic indicator is zhong (Old Chinese *k-lju), which by itself means "middle". In this case it can be seen that the pronunciation of the character is slightly different from that of its phonetic indicator; the process of historical phonetic change means that the composition of such characters can sometimes seem arbitrary today.

What is the process of historical phonetic change?
---
A: phonetic indicator

Problem: Federal Bureau of Investigation:

After Congress passed the Communications Assistance for Law Enforcement Act (CALEA, 1994), the Health Insurance Portability and Accountability Act (HIPAA, 1996), and the Economic Espionage Act (EEA, 1996), the FBI followed suit and underwent a technological upgrade in 1998, just as it did with its CART team in 1991. Computer Investigations and Infrastructure Threat Assessment Center (CITAC) and the National Infrastructure Protection Center (NIPC) were created to deal with the increase in Internet-related problems, such as computer viruses, worms, and other malicious programs that threatened US operations. With these developments, the FBI increased its electronic surveillance in public safety and national security investigations, adapting to the telecommunications advancements that changed the nature of such problems.

What team underwent a technological downgrade in 1991?
---
A: unanswerable

Problem: Apollo:

On the occasion of a pestilence in the 430s BCE, Apollo's first temple at Rome was established in the Flaminian fields, replacing an older cult site there known as the "Apollinare". During the Second Punic War in 212 BCE, the Ludi Apollinares ("Apollonian Games") were instituted in his honor, on the instructions of a prophecy attributed to one Marcius. In the time of Augustus, who considered himself under the special protection of Apollo and was even said to be his son, his worship developed and he became one of the chief gods of Rome.

Where was Apollo's first temple at Rome established?

A:
Flaminian fields
