Answer:
They are unsightly and hazardous to the residents in my neighborhood and the residents of Blueville.
Step-by-step explanation:
A writer's claim is the main argument that is made by the writer. This can be about anything, which can be backed with evidence supporting the claim.
In the given passage, Tricia's claim is that the placement of billboards is "unsightly and hazardous to the residents [of her neighborhood] and the residents of Blueville." This is because such billboards "advertised everything from services to personal care products to businesses inappropriate for young children." It's for this reason that she opposes the placing of billboards around the neighborhood.
Thus, the statement that best serves as the writer's claim is
"They are unsightly and hazardous to the residents in my neighborhood and the residents of Blueville."
