Problem: Chopin's mazurkas and waltzes are all in straightforward ternary or episodic form, sometimes with a coda. The mazurkas often show more folk features than many of his other works, sometimes including modal scales and harmonies and the use of drone basses. However, some also show unusual sophistication, for example Op. 63 No. 3, which includes a canon at one beat's distance, a great rarity in music.
What form are Chopin's mazurkas and waltzes in?
The answer is the following: straightforward ternary or episodic form, sometimes with a coda.


The site of Richmond had been an important village of the Powhatan Confederacy, and was briefly settled by English colonists from Jamestown in 1609, and in 1610–1611. The present city of Richmond was founded in 1737. It became the capital of the Colony and Dominion of Virginia in 1780. During the Revolutionary War period, several notable events occurred in the city, including Patrick Henry's "Give me liberty or give me death" speech in 1775 at St. John's Church, and the passage of the Virginia Statute for Religious Freedom written by Thomas Jefferson. During the American Civil War, Richmond served as the capital of the Confederate States of America. The city entered the 20th century with one of the world's first successful electric streetcar systems, as well as a national hub of African-American commerce and culture, the Jackson Ward neighborhood.
what famous speech did Patrick Henry give in Richmond?
Give me liberty or give me death


Input: Treaty
Consent will also be invalidated if it was induced by the fraudulent conduct of another party, or by the direct or indirect "corruption" of its representative by another party to the treaty. Coercion of either a representative, or the state itself through the threat or use of force, if used to obtain the consent of that state to a treaty, will invalidate that consent.

What type of action, either direct or indirect, of a state's representative by another type of party to a treaty can invalidate a state's consent?
Output: corruption


Input: Article: The native language of Germans is German, a West Germanic language, related to and classified alongside English and Dutch, and sharing many similarities with the North Germanic and Scandinavian languages. Spoken by approximately 100 million native speakers, German is one of the world's major languages and the most widely spoken first language in the European Union. German has been replaced by English as the dominant language of science-related Nobel Prize laureates during the second half of the 20th century. It was a lingua franca in the Holy Roman Empire.

Now answer this question: What is the most commonly spoken language in the European Union?

Output: German


Article: Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring with the major exception being overhead electric power transmission where aluminium is often preferred. Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Electrical wiring is the most important market for the copper industry. This includes building wire, communications cable, power distribution cable, appliance wire, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, solderability, and ease of installation.

Question: What is one property of copper that makes it so useful in electrical wiring?
Ans: high electrical conductivity


Input: Computer
During World War II, the British at Bletchley Park achieved a number of successes at breaking encrypted German military communications. The German encryption machine, Enigma, was first attacked with the help of the electro-mechanical bombes. To crack the more sophisticated German Lorenz SZ 40/42 machine, used for high-level Army communications, Max Newman and his colleagues commissioned Flowers to build the Colossus. He spent eleven months from early February 1943 designing and building the first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February.

Where did the British crack secret German military communications during World War II?
Output:
Bletchley Park
