Problem: Chihuahua (state):

In consequence to the Reform War, the federal government was bankrupt and could not pay its foreign debts to Spain, England, and France. On July 17, 1861, President Juarez decreed a moratorium on payment to foreign debtors for a period of two years. Spain, England, and France did not accept the moratorium by Mexico; they united at the Convention of the Triple Alliance on October 31, 1861 in which they agreed to take possession of several custom stations within Mexico as payment. A delegation of the Triple Alliance arrived in Veracruz in December 1861. President Juarez immediately sent his Foreign Affairs Minister, Manuel Doblado, who is able to reduce the debts through the Pacto de Soledad (Soledad Pact). General Juan Prim of Spain persuaded the English delegation to accept the terms of the Pacto de Soledad, but the French delegation refused.

Problem: Guam:

Guam is served by the Antonio B. Won Pat International Airport, which is a hub for United Airlines. The island is outside the United States customs zone so Guam is responsible for establishing and operating its own customs and quarantine agency and jurisdiction. Therefore, the U.S. Customs and Border Protection only carries immigration (but not customs) functions. Since Guam is under federal immigration jurisdiction, passengers arriving directly from the United States skip immigration and proceed directly to Guam Customs and Quarantine.

Where was Antonio B. Won Pat from originally?

A: unanswerable

Problem: Frederic Chopin:

Chopin also endowed popular dance forms with a greater range of melody and expression. Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form. His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance-floor equivalents.

What did Chopin add to the modern dance of his era?
---
A: greater range of melody and expression.
