Questions: Why did the Committee to Test the Separate Car Act choose Homer Plessy? A. Because he looked white B. Because he voted for the Populist Party C. Because he looked black and was from Louisiana D. Because he made powerful public statements

The answer is A. Because he looked white

Homer Plessy was chosen by the Committee to Test the Separate Car Act because he was of mixed race and could "pass" as white. This characteristic was crucial for the test case, as it would highlight the arbitrary and discriminatory nature of the segregation laws. Plessy was seven-eighths white and one-eighth black, which made him an ideal candidate to challenge the law.

There is no historical evidence to suggest that Plessy's voting record or political affiliations were a factor in his selection for the test case.

While Plessy was from Louisiana, the key reason for his selection was his ability to pass as white, not his appearance as black.

Homer Plessy was not particularly known for making powerful public statements. His selection was based on his racial appearance and the strategic legal challenge it posed to segregation laws.
