Problem: Electric recording which developed during the time that early radio was becoming popular (1925) benefited from the microphones and amplifiers used in radio studios. The early electric recordings were reminiscent tonally of acoustic recordings, except there was more recorded bass and treble as well as delicate sounds and overtones cut on the records. This was in spite of some carbon microphones used, which had resonances that colored the recorded tone. The double button carbon microphone with stretched diaphragm was a marked improvement. Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones.

Problem: Due to insistence by the International Federation of Association Football (FIFA), the international governing body of football, that domestic leagues reduce the number of games clubs played, the number of clubs was reduced to 20 in 1995 when four teams were relegated from the league and only two teams promoted. On 8 June 2006, FIFA requested that all major European leagues, including Italy's Serie A and Spain's La Liga be reduced to 18 teams by the start of the 200708 season. The Premier League responded by announcing their intention to resist such a reduction. Ultimately, the 200708 season kicked off again with 20 teams.
Since which year has FIFA been the governing body of football?

Problem: The term "Hispanic" as an ethnonym emerged in the 20th century with the rise of migration of laborers from the Spanish-speaking countries of Latin America to the United States. Today, the word "Latino" is often used as a synonym for "Hispanic". The definitions of both terms are non-race specific, and include people who consider themselves to be of distinct races (Black, White, Amerindian, Asian, and mixed groups). However, there is a common misconception in the US that Hispanic/Latino is a race or sometimes even that national origins such as Mexican, Cuban, Colombian, Salvadoran, etc. are races. In contrast to "Latino" or "Hispanic", "Anglo" refers to non-Hispanic White Americans or non-Hispanic European Americans, most of whom speak the English language but are not necessarily of English descent.
When did the term "Hispanic" begin being used?

the 20th century
