Problem: Extract the answer to the question from the following context. Question: What caused the massive amounts of chalk in the Cretaceous period? Context: To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activityor rather, the circulation of seawater through the enlarged ridgesenriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.

A: Mid-ocean ridge activity

Problem: Extract the answer to the question from the following context. Question: What would have encouraged average, non-scientific types to read the book? Context: In the 12th century CE the Andalusian Muslim philosopher and novelist Abu Bakr Ibn Tufail (known as "Abubacer" or "Ebn Tophail" in the West) included the theory of tabula rasa as a thought experiment in his Arabic philosophical novel, Hayy ibn Yaqdhan in which he depicted the development of the mind of a feral child "from a tabula rasa to that of an adult, in complete isolation from society" on a desert island, through experience alone. The Latin translation of his philosophical novel, entitled Philosophus Autodidactus, published by Edward Pococke the Younger in 1671, had an influence on John Locke's formulation of tabula rasa in An Essay Concerning Human Understanding.

A: he depicted the development of the mind of a feral child "from a tabula rasa to that of an adult, in complete isolation from society" on a desert island, through experience alone

Problem: Extract the answer to the question from the following context. Question: What has Utrecht Centraal railway on one side, and the city centre on the other side? Context: A large indoor shopping centre Hoog Catharijne (nl) is located between Utrecht Centraal railway station and the city centre. The corridors are treated as public places like streets, and the route between the station and the city centre is open all night. In 20 years from 2004, parts of Hoog Catharijne will be redeveloped as part of the renovation of the larger station area. Parts of the city's network of canals, which were filled to create the shopping center and central station area, will be recreated. The Jaarbeurs, one of the largest convention centres in the Netherlands, is located at the west side of the central railway station.

A: Hoog Catharijne

Problem: Extract the answer to the question from the following context. Question: What were some rewards for IBM employees? Context: IBM's employee management practices can be traced back to its roots. In 1914, CEO Thomas J. Watson boosted company spirit by creating employee sports teams, hosting family outings, and furnishing a company band. IBM sports teams still continue in the present day; the IBM Big Blue continue to exist as semi-professional company rugby and American football teams. In 1924 the Quarter Century Club, which recognizes employees with 25 years of service, was organized and the first issue of Business Machines, IBM's internal publication, was published. In 1925, the first meeting of the Hundred Percent Club, composed of IBM salesmen who meet their quotas, convened in Atlantic City, New Jersey.

A:
