Thoreau began speaking against slavery in public, echoing the voices of freedmen like frederick douglass and lewis hayden.
in this context, what does the word echoing mean?
speaking with the same tempo
speaking with the same words
speaking with the same conviction
speaking with the same audiences

The answer is C: Speaking with the same conviction since that is what the word echoing means when you read the context, "Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden."

Hope this helped!
