Problem: Queen drew artistic influence from British rock acts of the 1960s and early 1970s, such as the Beatles, the Kinks, Cream, Led Zeppelin, Pink Floyd, the Who, Black Sabbath, Slade, Deep Purple, David Bowie, Genesis and Yes, in addition to American guitarist Jimi Hendrix, with Mercury also inspired by the gospel singer Aretha Franklin. May referred to the Beatles as being "our bible in the way they used the studio and they painted pictures and this wonderful instinctive use of harmonies." At their outset in the early 1970s, Queen's music has been characterised as "Led Zeppelin meets Yes" due to its combination of "acoustic/electric guitar extremes and fantasy-inspired multi-part song epics".
What band named after a floating vehicle influenced Queen?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The town's first significant defences were likely erected due to commercial interests, following the temporary seizure of St. John's by the Dutch admiral Michiel de Ruyter in June 1665. The inhabitants were able to fend off a second Dutch attack in 1673, when this time it was defended by Christopher Martin, an English merchant captain. Martin landed six cannons from his vessel, the Elias Andrews, and constructed an earthen breastwork and battery near chain Rock commanding the Narrows leading into the harbour. With only twenty-three men, the valiant Martin beat off an attack by three Dutch warships. The English government planned to expand these fortifications (Fort William) in around 1689, but actual construction didn't begin until after the French admiral Pierre Le Moyne d'Iberville captured and destroyed the town in the Avalon Peninsula Campaign (1696). When 1500 English reinforcements arrived in late 1697 they found nothing but rubble where the town and fortifications had stood.
Who briefly seized St. John's in 1665?
A: Michiel de Ruyter

Context and question: Hunting and gathering was presumably the subsistence strategy employed by human societies beginning some 1.8 million years ago, by Homo erectus, and from its appearance some 0.2 million years ago by Homo sapiens. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago, and after this was replaced only gradually with the spread of the Neolithic Revolution.
Which subsistence strategy started with the Neolithic Revolution?
Answer: unanswerable

Question: The culture of Eritrea has been largely shaped by the country's location on the Red Sea coast. One of the most recognizable parts of Eritrean culture is the coffee ceremony. Coffee (Ge'ez bun) is offered when visiting friends, during festivities, or as a daily staple of life. During the coffee ceremony, there are traditions that are upheld. The coffee is served in three rounds: the first brew or round is called awel in Tigrinya meaning first, the second round is called kalaay meaning second, and the third round is called bereka meaning "to be blessed". If coffee is politely declined, then most likely tea ("shai" shahee) will instead be served.
Is there an answer to this question: What is the third round of coffee called in Italian?

Answer: unanswerable

Problem: Slavs:

The Slavic autonym is reconstructed in Proto-Slavic as *Slovenin, plural *Slovene. The oldest documents written in Old Church Slavonic and dating from the 9th century attest Slovene to describe the Slavs. Other early Slavic attestations include Old East Slavic Slovene for "an East Slavic group near Novgorod." However, the earliest written references to the Slavs under this name are in other languages. In the 6th century AD Procopius, writing in Byzantine Greek, refers to the Sklaboi, Sklabenoi, Sklauenoi, Sthlabenoi, or Sklabinoi, while his contemporary Jordanes refers to the Sclaveni in Latin.

Procopius' contemporary Jordanes referred to the Slavs in what language?
---
A:
Latin
