Answer:
Personal Attacks
Negative Stereotyping
Positive Stereotyping
Explanation:
Personal attacks are bias that appear when an individual makes abusive accusations about a group of individuals, without presenting any argument or fact that proves that accusation. In the text above this can be seen in the line "idle, muddle-headed aristocrats". This line also represents the Negative Stereotyping bias, as it provides a stereotype to a group of people in a negative way, showing defects that are "common" to all members of that group.
The last bias presented is Positive Stereotyping, which refers to the establishment of qualities aimed at a group in a generalized way, as if all members have this quality. An example of this can be seen in the line "Some of these beautiful, intelligent animals escaped and established herds of their own"
