Correct Answer - Option 4 :
Neither I nor II follows.
The statement mentions that Wheatly was the first African American to publish a book. It was a remarkable achievement because during that time slaves were not even considered humans.
From what has been supplied we only know that she was the first African American to get a book published, in very unfavorable situations but cannot deduce that no other African American prior to Wheatly was educated. Also, we do not know for sure that Wheatly was a lady. Therefore, the inference I does not follow.
The statement recognizes the publishing of books as an achievement since slaves at that point in time were not even considered humans. We know that Wheatly was an African American and the reference has been made to Colonial America. But it is not definite that Wheatly was also a slave. So the inference II does not follow.
Hence, Neither I nor II follows.
