Answer:
The viewpoint is contained in the sentence:
The overwhelming number of geese at the park has become unacceptable.
Step-by-step explanation:
A viewpoint is an expression of opinion or judgement by the narrator of a story based on his or her observations or evidence. It is most often expressed in a paragraph after the plot (which is a narration of events). In this paragraph from a letter, the main topic or theme is "The Situation at the Downtown Park." This is followed by the topic sentence, and then the events that happened at the park. In conclusion, the writer expresses her opinion about her observations and experiences. Recommendations usually follow the viewpoint.
