The correct answer is B. It focuses on facts about mush without including Douglass's own opinion of it.
Step-by-step explanation:
In this excerpt, Douglass provides information about the way children and adults were feed as they were all slaves. Moreover, in this text, Douglass mainly describes the food called "mush" and the way this was provided without including his opinion or feelings about this. This can be seen in ideas such as "was coarse corn-meal boiled" or "set down upon the ground". This characteristic makes the text to be objective as there is a focus on facts and the personal opinion of the author is not included. According to this, the correct answer is B.
