11. Which statement from President Polk's address is a fact rather than an opinion?

Answer: B

Explanation:

B: "[O]ur people have filled the eastern valley of the Mississippi,... ascended the Missouri to its headsprings..."

This statement is a fact because it presents a verifiable historical account of the movement of American settlers, indicating that they occupied specific geographic areas. It does not reflect a subjective belief or interpretation.

A) "Our title to Oregon is 'clear and unquestionable,' and already are our people preparing to perfect that title by occupying it with their wives and children..."

This statement expresses an opinion regarding the legitimacy of the United States' claim to Oregon, using subjective language like "clear and unquestionable." It does not present a verifiable fact but rather a belief about ownership and future intentions.

C) "Nor will it become in a less degree my duty to maintain by all constitutional means the right of the United States to that portion of our territory which lies beyond the Rocky Mountains."

This statement conveys a commitment or opinion regarding the duty of the government to uphold territorial rights. It reflects a personal stance rather than a factual assertion that can be independently verified.

D) "The jurisdiction of our laws and the benefits of our republican institutions should be extended over them in the distant regions which they have selected for their homes."

This statement is opinion-based because it suggests a preference for extending jurisdiction and benefits, rather than providing a factual description of current situations. It articulates a belief about governance and rights rather than a verifiable claim.

Conclusion

The correct answer, option B, stands out as a factual statement grounded in historical realities about American settlement patterns. In contrast, options A, C, and D reflect subjective opinions on territorial claims and governance, lacking the verifiability that characterizes a fact. Thus, B is the only choice that conveys an objective truth based on historical context.
