Answer:
"They are... very pretty."
This sentence expresses a personal opinion or judgment about the appearance of the sheep, using the adjective "pretty" to describe them. The use of this word implies a subjective evaluation, as beauty is a matter of personal taste.
The other options do not show a subjective perspective:
"They have sheep here that have no ears." is a factual statement about the physical characteristics of the sheep. "Their domestic animals... are fed on fish." is a factual statement about the diet of the domestic animals. "In all this country... there is no grass." is a factual statement about the environment. These sentences provide objective information, whereas the statement about the sheep being "very pretty" is a subjective interpretation.
Explanation:
So the sentence "They are... very pretty" is an example of a subjective perspective because it expresses a personal opinion or judgment about the appearance of the sheep, using the adjective "pretty" which is a matter of personal taste.
