Context: The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier.???

input question: Extract the answer to the question from the following context. Question: In the article, what word is used to define each person from Africa specifically? Context: These patterns of discrimination against non-whites have led some academic and other activists to advocate for use of the Portuguese term negro to encompass all African-descended people, in order to stimulate a "black" consciousness and identity. This proposal has been criticized since the term pardo is considered to include a wide range of multiracial people, such as caboclos (mestizos), assimilated Amerindians and tri-racials, not only people of partial African and European descent. Trying to identify this entire group as "black" would be a false imposition of a different identity from outside the culture and deny people their other, equally valid, ancestries and cultures. It seems a one-drop rule in reverse.???
output answer: negro

input question: Extract the answer to the question from the following context. Question: What colors do the Fighting Irish officially wear? Context: Notre Dame's conference affiliations for all of its sports except football and fencing changed in July 2013 as a result of major conference realignment, and its fencing affiliation will change in July 2014. The Irish left the Big East for the ACC during a prolonged period of instability in the Big East; while they maintain their football independence, they have committed to play five games per season against ACC opponents. In ice hockey, the Irish were forced to find a new conference home after the Big Ten Conference's decision to add the sport in 2013–14 led to a cascade of conference moves that culminated in the dissolution of the school's former hockey home, the Central Collegiate Hockey Association, after the 2012–13 season. Notre Dame moved its hockey team to Hockey East. After Notre Dame joined the ACC, the conference announced it would add fencing as a sponsored sport beginning in the 2014–15 school year. There are many theories behind the adoption of the athletics moniker but it is known that the Fighting Irish name was used in the early 1920s with respect to the football team and was popularized by alumnus Francis Wallace in his New York Daily News columns. The official colors of Notre Dame are Navy Blue and Gold Rush which are worn in competition by its athletic teams. In addition, the color green is often worn because of the Fighting Irish nickname. The Notre Dame Leprechaun is the mascot of the athletic teams. Created by Theodore W. Drake in 1964, the leprechaun was first used on the football pocket schedule and later on the football program covers. The leprechaun was featured on the cover of Time in November 1964 and gained national exposure.???
output answer: Navy Blue and Gold Rush

input question: Extract the answer to the question from the following context. Question: What facet of the workings of the software giant owned by a man named Gates functions both as a boon to that software giant and also a possible threat to national security? Context: In June 2014, state broadcaster China Central Television (CCTV) broadcast a news story further characterizing Windows 8 as a threat to national security. The story featured an interview with Ni Guangnan, who stated that operating systems could aggregate "sensitive user information" that could be used to "understand the conditions and activities of our national economy and society", and alleged that per documents leaked by Edward Snowden, the U.S. government had worked with Microsoft to retrieve encrypted information. Yang Min, a computer scientist at Fudan University, also stated that "the security features of Windows 8 are basically to the benefit of Microsoft, allowing them control of the users' data, and that poses a big challenge to the national strategy for information security." Microsoft denied the claims in a number of posts on the Chinese social network Sina Weibo, which stated that the company had never "assisted any government in an attack of another government or clients" or provided client data to the U.S. government, never "provided any government the authority to directly visit" or placed any backdoors in its products and services, and that it had never concealed government requests for client data.???

control of the users' data
