Problem: Palermo:

The city was founded in 734 BC by the Phoenicians as Ziz ('flower'). Palermo then became a possession of Carthage, before becoming part of the Roman Republic, the Roman Empire and eventually part of the Byzantine Empire, for over a thousand years. The Greeks named the city Panormus meaning 'complete port'. From 831 to 1072 the city was under Arab rule during the Emirate of Sicily when the city first became a capital. The Arabs shifted the Greek name into Balarm, the root for Palermo's present-day name. Following the Norman reconquest, Palermo became the capital of a new kingdom (from 1130 to 1816), the Kingdom of Sicily and the capital of the Holy Roman Empire under Frederick II Holy Roman Emperor and Conrad IV of Germany, King of the Romans. Eventually Sicily would be united with the Kingdom of Naples to form the Kingdom of the Two Sicilies until the Italian unification of 1860.

What group of people founded Palermo?
---
A: the Phoenicians


Problem: The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source (44,100 samples per second × 16 bits per sample × 2 channels = 1,411,200 bit/s; MP3 compressed at 128 kbit/s: 128,000 bit/s [1 k = 1,000, not 1024, because it is a bit rate]. Ratio: 1,411,200/128,000 = 11.025). An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality.
How many total bit/s would a CD have?

Answer: 1,411,200


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Since the armature windings of a direct-current or universal motor are moving through a magnetic field, they have a voltage induced in them. This voltage tends to oppose the motor supply voltage and so is called "back electromotive force (emf)". The voltage is proportional to the running speed of the motor. The back emf of the motor, plus the voltage drop across the winding internal resistance and brushes, must equal the voltage at the brushes. This provides the fundamental mechanism of speed regulation in a DC motor. If the mechanical load increases, the motor slows down; a lower back emf results, and more current is drawn from the supply. This increased current provides the additional torque to balance the new load.
 ENP is proportional to what?
A: unanswerable


Context and question: Rome had a semi-divine ancestor in the Trojan refugee Aeneas, son of Venus, who was said to have established the nucleus of Roman religion when he brought the Palladium, Lares and Penates from Troy to Italy. These objects were believed in historical times to remain in the keeping of the Vestals, Rome's female priesthood. Aeneas had been given refuge by King Evander, a Greek exile from Arcadia, to whom were attributed other religious foundations: he established the Ara Maxima, "Greatest Altar," to Hercules at the site that would become the Forum Boarium, and he was the first to celebrate the Lupercalia, an archaic festival in February that was celebrated as late as the 5th century of the Christian era.
What mythical figure did the Romans consider to be semi-divine?
Answer: Aeneas


Question: Like other languages, Catalan has a large list of learned words from Greek and Latin. This process started very early, and one can find such examples in Ramon Llull's work. On the fourteenth and fifteenth centuries Catalan had a number of Greco-Latin learned words much superior to other Romance languages, as it can be attested for example in Roís de Corella's writings.
Is there an answer to this question: Where does Catalan get a lot of its learned words?

Answer: Greek and Latin


Question: Two of Chopin's long-standing pupils, Karol Mikuli (1821–1897) and Georges Mathias, were themselves piano teachers and passed on details of his playing to their own students, some of whom (such as Raoul Koczalski) were to make recordings of his music. Other pianists and composers influenced by Chopin's style include Louis Moreau Gottschalk, Édouard Wolff (1816–1880) and Pierre Zimmermann. Debussy dedicated his own 1915 piano Études to the memory of Chopin; he frequently played Chopin's music during his studies at the Paris Conservatoire, and undertook the editing of Chopin's piano music for the publisher Jacques Durand.
Is there an answer to this question: What music did Debussy play a lot at the Paris Conservatoire?

Answer:
Chopin's
