Questions: Which group in nineteenth-century America would likely be the most receptive audience for "What to the Slave is the Fourth of July?" enslavers abolitionists dock workers clergy

The answer is: abolitionists.

Explanation for each option:

1. Enslavers: This group would likely be the least receptive to "What to the Slave is the Fourth of July?" as the speech, delivered by Frederick Douglass, is a powerful critique of slavery and the hypocrisy of celebrating freedom in a nation that permits slavery. Enslavers, who benefited from the institution of slavery, would likely be opposed to its message.

2. Abolitionists: Abolitionists would be the most receptive audience for this speech. They were actively working to end slavery and would have supported Douglass's arguments highlighting the injustices and moral contradictions of slavery in America. The speech would resonate with their beliefs and efforts to promote equality and freedom for all.

3. Dock workers: While dock workers might have varied opinions, they were not specifically aligned with the abolitionist movement as a group. Some might have been sympathetic to the abolitionist cause, especially if they were part of the working class that opposed slavery on economic or moral grounds, but they were not the primary audience for Douglass's speech.

4. Clergy: The clergy could have mixed reactions. Some members of the clergy were abolitionists and would support Douglass's message, while others might have been more conservative or aligned with pro-slavery sentiments, depending on their denomination and personal beliefs. Therefore, they would not be as uniformly receptive as abolitionists.
