Problem: Bermuda:

Bermuda is a group of low-forming volcanoes located in the Atlantic Ocean, near the western edge of the Sargasso Sea, roughly 578 nautical miles (1,070 km (665 mi)) east-southeast of Cape Hatteras on the Outer Banks of North Carolina and about 594 nautical miles (1,100 km (684 mi)) southeast of Martha's Vineyard of Massachusetts.

Problem: Recent research indicates that the specialized animals that formed complex ecosystems, with high biodiversity, complex food webs and a variety of niches, took much longer to reestablish, recovery did not begin until the start of the mid-Triassic, 4M to 6M years after the extinction and was not complete until 30M years after the PermianTriassic extinction event. Animal life was then dominated by various archosaurian reptiles: dinosaurs, pterosaurs, and aquatic reptiles such as ichthyosaurs, plesiosaurs, and mosasaurs.
What type of animals were especially quick to reestablish?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1981 a team of researchers from the Maison de l'Orient et de la Mediterranee, including Jacques Cauvin and Oliver Aurenche divided Near East neolithic chronology into ten periods (0 to 9) based on social, economic and cultural characteristics. In 2002 Danielle Stordeur and Frederic Abbes advanced this system with a division into five periods. Natufian (1) between 12,000 and 10,200 BC, Khiamian (2) between 10,200-8,800 BC, PPNA: Sultanian (Jericho), Mureybetian, early PPNB (PPNB ancien) (3) between 8,800-7,600 BC, middle PPNB (PPNB moyen) 7,600-6,900 BC, late PPNB (PPNB recent) (4) between 7,500 and 7,000 BC and a PPNB (sometimes called PPNC) transitional stage (PPNB final) (5) where Halaf and dark faced burnished ware begin to emerge between 6,900-6,400 BC. They also advanced the idea of a transitional stage between the PPNA and PPNB between 8,800 and 8,600 BC at sites like Jerf el Ahmar and Tell Aswad.
Who advanced the idea of a final stage between the PPNA and PPNB?
A: unanswerable

Context and question: Instruments like the duduk, the dhol, the zurna, and the kanun are commonly found in Armenian folk music. Artists such as Sayat Nova are famous due to their influence in the development of Armenian folk music. One of the oldest types of Armenian music is the Armenian chant which is the most common kind of religious music in Armenia. Many of these chants are ancient in origin, extending to pre-Christian times, while others are relatively modern, including several composed by Saint Mesrop Mashtots, the inventor of the Armenian alphabet. Whilst under Soviet rule, Armenian classical music composer Aram Khatchaturian became internationally well known for his music, for various ballets and the Sabre Dance from his composition for the ballet Gayane.
What is known as one of the most prolific type of religious music in Armenia?
Answer: the Armenian chant

Question: The 1910 election saw 42 Labour MPs elected to the House of Commons, a significant victory since, a year before the election, the House of Lords had passed the Osborne judgment ruling that Trades Unions in the United Kingdom could no longer donate money to fund the election campaigns and wages of Labour MPs. The governing Liberals were unwilling to repeal this judicial decision with primary legislation. The height of Liberal compromise was to introduce a wage for Members of Parliament to remove the need to involve the Trade Unions. By 1913, faced with the opposition of the largest Trades Unions, the Liberal government passed the Trade Disputes Act to allow Trade Unions to fund Labour MPs once more.
Is there an answer to this question: What did the House of Lords pass a year after the election?

Answer: unanswerable

Problem: Clothing:

Clothing can and has in history been made from a very wide variety of materials. Materials have ranged from leather and furs, to woven materials, to elaborate and exotic natural and synthetic fabrics. Not all body coverings are regarded as clothing. Articles carried rather than worn (such as purses), worn on a single part of the body and easily removed (scarves), worn purely for adornment (jewelry), or those that serve a function other than protection (eyeglasses), are normally considered accessories rather than clothing, as are footwear and hats.

What are footwear and hats both considered?
---
A:
accessories
