Answer:
C.An uneducated slave, played by a white man in a black face .
Explanation:
Throughout the 1830s and '40s, the white entertainer Thomas Dartmouth Rice (1808-1860) performed a popular song-and-dance act supposedly modeled after a slave. He named the character Jim Crow. Rice darkened his face, acted like a buffoon, and spoke with an exaggerated and distorted imitation of African American Vernacular English. In his Jim Crow persona, he also sang "Negro ditties" such as "Jump Jim Crow." Rice was not the first white comic to perform in blackface, but he was the most popular of his time, touring both the United States and England. As a result of Rice's success, "Jim Crow" became a common stage persona for white comedians' blackface portrayals of African Americans.
The first and foremost merit of Protestant Reformation is that it dispensed with one, unique, and unquestionable authority, embodied in the Roman Catholic Church. It opened the path to pluralism - a multitude of opinions that seek to be freely expressed, without censure and fear of punishment. It dismantled the dogma of one truth and one truth only - whether it be about God, Trinity, priests, an attitude towards worldly riches or anything else. Even though it was not secular, its focus on living in this world rather than in anticipation of heaven or hell, opened new perspectives for the development of secularism too.
