Article: By the 1900s, nigger had become a pejorative word in the United States. In its stead, the term colored became the mainstream alternative to negro and its derived terms. After the African-American Civil rights movement, the terms colored and negro gave way to "black". Negro had superseded colored as the most polite word for African Americans at a time when black was considered more offensive. This term was accepted as normal, including by people classified as Negroes, until the later Civil Rights movement in the late 1960s. One well-known example is the identification by Reverend Martin Luther King, Jr. of his own race as "Negro" in his famous speech of 1963, I Have a Dream. During the American Civil Rights movement of the 1950s and 1960s, some African-American leaders in the United States, notably Malcolm X, objected to the word Negro because they associated it with the long history of slavery, segregation, and discrimination that treated African Americans as second-class citizens, or worse. Malcolm X preferred Black to Negro, but later gradually abandoned that as well for Afro-American after leaving the Nation of Islam.

Question: What term followed "negro" and "colored"?
Ans: "black"

Article: 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.

Question: What type of microphones were losing popularity in the 1920s?
Ans: carbon microphones used,
