Input: Read this: Southern Italy was also part of the Norman kingdom but great mosaics did not survive in this area except the fine mosaic pavement of the Otranto Cathedral from 1166, with mosaics tied into a tree of life, mostly still preserved. The scenes depict biblical characters, warrior kings, medieval beasts, allegories of the months and working activity. Only fragments survived from the original mosaic decoration of Amalfi's Norman Cathedral. The mosaic ambos in the churches of Ravello prove that mosaic art was widespread in Southern Italy during the 11th–13th centuries.
Question: What year were the mosaic pavements installed at the Otranto Cathedral?

Output: 1166


Input: Read this: Antarctica continued to become more isolated and finally developed a permanent ice cap. Mountain building in western North America continued, and the Alps started to rise in Europe as the African plate continued to push north into the Eurasian plate, isolating the remnants of Tethys Sea. A brief marine incursion marks the early Oligocene in Europe. There appears to have been a land bridge in the early Oligocene between North America and Europe since the faunas of the two regions are very similar. During the Oligocene, South America was finally detached from Antarctica and drifted north toward North America. It also allowed the Antarctic Circumpolar Current to flow, rapidly cooling the continent.
Question: Which current resulted in the cooling of Antarctica?

Output: the Antarctic Circumpolar Current


Input: Read this: A 2011 study by the Translational Genomics Research Institute showed that 47% of the meat and poultry sold in United States grocery stores was contaminated with Staphylococcus aureus, and 52% of the bacteria concerned showed resistance to at least three groups of antibiotics. Thorough cooking of the product would kill these bacteria, but a risk of cross-contamination from improper handling of the raw product is still present. Also, some risk is present for consumers of poultry meat and eggs to bacterial infections such as Salmonella and Campylobacter. Poultry products may become contaminated by these bacteria during handling, processing, marketing, or storage, resulting in food-borne illness if the product is improperly cooked or handled.
Question: Why can't bacteria enter poultry?

Output: unanswerable


Input: Read this: West's third studio album, Graduation, garnered major publicity when its release date pitted West in a sales competition against rapper 50 Cent's Curtis. Upon their September 2007 releases, Graduation outsold Curtis by a large margin, debuting at number one on the U.S. Billboard 200 chart and selling 957,000 copies in its first week. Graduation once again continued the string of critical and commercial successes by West, and the album's lead single, "Stronger", garnered the rapper his third number-one hit. "Stronger", which samples French house duo Daft Punk, has been accredited to not only encouraging other hip-hop artists to incorporate house and electronica elements into their music, but also for playing a part in the revival of disco and electro-infused music in the late 2000s. Ben Detrick of XXL cited the outcome of the sales competition between 50 Cent's Curtis and West's Graduation as being responsible for altering the direction of hip-hop and paving the way for new rappers who didn't follow the hardcore-gangster mold, writing, "If there was ever a watershed moment to indicate hip-hop's changing direction, it may have come when 50 Cent competed with Kanye in 2007 to see whose album would claim superior sales."
Question: Kanye released Graduation at the same time of what other famous rapper, thus drawing media comparison?

Output:
50 Cent
