Problem: John von Neumann:

Von Neumann was a founding figure in computing. Donald Knuth cites von Neumann as the inventor, in 1945, of the merge sort algorithm, in which the first and second halves of an array are each sorted recursively and then merged. Von Neumann wrote the sorting program for the EDVAC in ink, being 23 pages long; traces can still be seen on the first page of the phrase "TOP SECRET", which was written in pencil and later erased. He also worked on the philosophy of artificial intelligence with Alan Turing when the latter visited Princeton in the 1930s.

Who was the inventor of the merge-sort algorithm?
---
A: Von Neumann

Ann Arbor has a council-manager form of government. The City Council has 11 voting members: the mayor and 10 city council members. The mayor and city council members serve two-year terms: the mayor is elected every even-numbered year, while half of the city council members are up for election annually (five in even-numbered and five in odd-numbered years). Two council members are elected from each of the city's five wards. The mayor is elected citywide. The mayor is the presiding officer of the City Council and has the power to appoint all Council committee members as well as board and commission members, with the approval of the City Council. The current mayor of Ann Arbor is Christopher Taylor, a Democrat who was elected as mayor in 2014. Day-to-day city operations are managed by a city administrator chosen by the city council.
Who is elected every even numbered year?
A: mayor


Context and question: An intellectual revitalization of Europe started with the birth of medieval universities in the 12th century. The contact with the Islamic world in Spain and Sicily, and during the Reconquista and the Crusades, allowed Europeans access to scientific Greek and Arabic texts, including the works of Aristotle, Ptolemy, Jābir ibn Hayyān, al-Khwarizmi, Alhazen, Avicenna, and Averroes. European scholars had access to the translation programs of Raymond of Toledo, who sponsored the 12th century Toledo School of Translators from Arabic to Latin. Later translators like Michael Scotus would learn Arabic in order to study these texts directly. The European universities aided materially in the translation and propagation of these texts and started a new infrastructure which was needed for scientific communities. In fact, European university put many works about the natural world and the study of nature at the center of its curriculum, with the result that the "medieval university laid far greater emphasis on science than does its modern counterpart and descendent."
Which translator learned Arabic to be able to study the Arabic texts directly?
Answer: Michael Scotus


Question: Spielberg was scheduled to shoot a $200 million adaptation of Daniel H. Wilson's novel Robopocalypse, adapted for the screen by Drew Goddard.

It was set for release on April 25, 2014, with Anne Hathaway and Chris Hemsworth set to star, but Spielberg postponed production indefinitely in January 2013, just before it had been set to begin.
Is there an answer to this question: Who wrote the book 'Robopocalypse' is based on?

Answer: Daniel H. Wilson


Often, large multinational corporations exhibit vertical integration, participating in a broad range of drug discovery and development, manufacturing and quality control, marketing, sales, and distribution. Smaller organizations, on the other hand, often focus on a specific aspect such as discovering drug candidates or developing formulations. Often, collaborative agreements between research organizations and large pharmaceutical companies are formed to explore the potential of new drug substances. More recently, multi-nationals are increasingly relying on contract research organizations to manage drug development.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of agreements are made to research potential new drugs?
Ah, so..
collaborative agreements
