In November 2014, the Bill and Melinda Gates Foundation announced that they are adopting an open access (OA) policy for publications and data, "to enable the unrestricted access and reuse of all peer-reviewed published research funded by the foundation, including any underlying data sets". This move has been widely applauded by those who are working in the area of capacity building and knowledge sharing.[citation needed] Its terms have been called the most stringent among similar OA policies. As of January 1, 2015 their Open Access policy is effective for all new agreements.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the OA policy cover ?
Ah, so.. As of January 1, 2015 their Open Access policy is effective for all new agreements.

In the nineteenth and twentieth centuries the RIBA and its members had a leading part in the promotion of architectural education in the United Kingdom, including the establishment of the Architects' Registration Council of the United Kingdom (ARCUK) and the Board of Architectural Education under the Architects (Registration) Acts, 1931 to 1938. A member of the RIBA, Lionel Bailey Budden, then Associate Professor in the Liverpool University School of Architecture, had contributed the article on Architectural Education published in the fourteenth edition of the Encyclopdia Britannica (1929). His School, Liverpool, was one of the twenty schools named for the purpose of constituting the statutory Board of Architectural Education when the 1931 Act was passed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many schools did not form the Board of Architectural Education?
Ah, so.. unanswerable

By the time of the Uruk period (c. 41002900 BC calibrated), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of slave labor captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide areafrom the Taurus Mountains in Turkey, to the Mediterranean Sea in the west, and as far east as central Iran.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During which period did Sumerian cities begin using slave labor?
Ah, so..
Uruk
