Final answer:
A rebuttal is included in the statement acknowledging Dixon's viewpoint but then challenging it by emphasizing the unconsidered impact on American Indians.
Step-by-step explanation:
The statement that includes a rebuttal is: "While I can see Dixon's point, it's clear that he hasn't considered how the monument will affect American Indians." This sentence acknowledges Dixon's argument before presenting a counterargument that challenges the consideration given to how the monument will impact American Indians. The use of rebuttal here is crucial as it shows an engagement with the opposing viewpoint and offers a critique based on perspectives and historic injustices highlighted in the provided references, such as Helen Hunt Jackson's work and the government's historical policy regarding Native Americans.
