Question

what is phrase is redundant and should be removed
after escaping slavery, Harriet Tubman became an abolitionist who bravely and courageously, helped hundreds of slaves reach freedom along the underground railroad

Answer 1

The phrase "bravely and courageously" is redundant because both words convey a similar meaning. You could simply say, "Harriet Tubman became an abolitionist who bravely helped hundreds of slaves reach freedom along the Underground Railroad." Alternatively, you could use either "bravely" or "courageously," but not both.
