9. Which of the following sentences requires citation?

Answer: D

Explanation:

There were buffalo in every western territory of the United States as of 1860.

This statement requires citation because it presents a factual claim regarding the presence of buffalo in western territories during a specific historical period. Such claims necessitate supporting evidence from historical records or scholarly sources to validate their accuracy.

A) At our school, we only learned about a fraction of the political and economic complexities of the American Civil War.

This sentence expresses a personal experience or opinion about education at a particular school. It does not present a verifiable fact that requires citation, as it reflects subjective learning experiences rather than objective information.

B) They say that the victors write history.

This statement is a generalization or a common saying that reflects a philosophical viewpoint about history. It does not require citation because it does not assert a factual claim that can be substantiated or disproven with evidence.

C) I would wager that most students in the United States will be able to tell you that the battle of Fort Sumter in 1861 started the American Civil War.

While this statement discusses a historical event, it is based on an assumption about the knowledge of students and does not present a fact that would necessitate citation. It reflects a conjecture rather than a definitive claim requiring evidence.

D) There were buffalo in every western territory of the United States as of 1860.

This statement makes a specific historical claim that can be verified or challenged through historical data and records. Therefore, it requires citation to support its accuracy and context within historical discussions.

Conclusion

The correct answer, option D, is the only statement that presents a specific factual claim about the presence of buffalo that can be verified and thus requires citation. All other options either reflect personal views, generalizations, or assumptions that do not necessitate supporting evidence, highlighting the importance of substantiating factual claims within academic discourse.
