Task: Question Answering
Input (English): Passage: Makeba married Carmichael in March 1968; this caused her popularity in the US to decline markedly. Conservatives came to regard her as a militant and an extremist, an image which alienated much of her fanbase. Her performances were cancelled and her coverage in the press declined despite her efforts to portray her marriage as apolitical. White American audiences stopped supporting her, and the US government took an interest in her activities. The Central Intelligence Agency began following her, and placed hidden microphones in her apartment; the Federal Bureau of Investigation also placed her under surveillance. While she and her husband were travelling in the Bahamas, she was banned from returning to the US, and was refused a visa. As a result, the couple moved to Guinea, where Carmichael changed his name to Kwame Touré. Makeba did not return to the US until 1987.Guinea remained Makeba's home for the next 15 years, and she and her husband became close to President Ahmed Sékou Touré and his wife, Andrée. Touré wanted to create a new style of African music, and all musicians received a minimum wage if they practised for several hours every day. Makeba later stated that "I've never seen a country that did what Sékou Touré did for artists." After her rejection from the US she began to write music more directly critical of the US government's racial policies, recording and singing songs such as "Lumumba" in 1970, (referring to Patrice Lumumba, the assassinated Prime Minister of the Congo), and "Malcolm X" in 1974. 
Question: What is the name of the person who recorded and sang songs such as "Lumumba" and "Malcom X," which were reportedly more directly critical of the US government's racial policies?
Output (English): Makeba.
