Problem: Please answer a question about the following article about 51st state:
Since 1898, Puerto Rico has had limited representation in the Congress in the form of a Resident Commissioner, a nonvoting delegate. The 110th Congress returned the Commissioner's power to vote in the Committee of the Whole, but not on matters where the vote would represent a decisive participation. Puerto Rico has elections on the United States presidential primary or caucus of the Democratic Party and the Republican Party to select delegates to the respective parties' national conventions although presidential electors are not granted on the Electoral College. As American citizens, Puerto Ricans can vote in U.S. presidential elections, provided they reside in one of the 50 states or the District of Columbia and not in Puerto Rico itself.
How long has Puerto Rico had representation in Congress?
A: Since 1898

About 10,000 years ago, when the ice melted after the last glacial period, late Paleolithic communities were established along the lake shores and in cave systems. Evidence of human habitation has been found in caves near Vercors, close to Grenoble; in Austria the Mondsee culture shows evidence of houses built on piles to keep them dry. Standing stones have been found in Alpine areas of France and Italy. The rock drawings in Valcamonica are more than 5000 years old; more than 200,000 drawings and etchings have been identified at the site.

What has been found in caves near Vercors?
Answer: Evidence of human habitation

Problem: Dante Alighieri's Divine Comedy, written in the early 14th century, merged a medieval world view with classical ideals. Another promoter of the Italian language was Boccaccio with his Decameron. The application of the vernacular did not entail a rejection of Latin, and both Dante and Boccaccio wrote prolifically in Latin as well as Italian, as would Petrarch later (whose Canzoniere also promoted the vernacular and whose contents are considered the first modern lyric poems). Together the three poets established the Tuscan dialect as the norm for the modern Italian language.
In what languages did Dante and Boccaccio create their works?
The answer is the following: Latin as well as Italian

Two major extant branches of Buddhism are generally recognized by scholars: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Vajrayana, a body of teachings attributed to Indian siddhas, may be viewed as a third branch or merely a part of Mahayana. Theravada has a widespread following in Sri Lanka and Southeast Asia. Mahayana which includes the traditions of Pure Land, Zen, Nichiren Buddhism, Shingon, and Tiantai (Tendai) is found throughout East Asia. Tibetan Buddhism, which preserves the Vajrayana teachings of eighth century India, is practiced in regions surrounding the Himalayas, Mongolia and Kalmykia. Buddhists number between an estimated 488 million[web 1] and 535 million, making it one of the world's major religions.
What kind of teachings does Tibetan Buddhism preserve?
Vajrayana

Problem: Please answer a question about the following article about Pitch (music):
The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).
All these different methods have what in common?
A:
the octave
