Answer:
The effects of slavery are so ingrained in American society that achieving equality for all will take patience.
Step-by-step explanation:
Booker T. Washington's "Up From Slavery" is a memoir that narrates his life from a slave to an educated abolitionist. Washington would also play an important part in the fight for slaves' freedom.
The given statement is said by Washington. The institution that he mentioned here is that of slavery, which he claims "[was introduced], recognized and protected for years by the General Government." Moreover, he also expressed his belief that "[the tentacles of slavery are] fastened [that] it was no easy matter for the country to relieve itself f the institution."
This shows that both Washington and Du Bois would agree that the effects of slavery are so ingrained in the American society that it will take a lot of patience to achieve equality for the slaves.
Thus, the correct answer is the third option.
