Final answer:
The text has two sentences with fluency errors that can be rectified. The first sentence needs a conjunction to correct the run-on, and the third sentence requires either a conjunction or punctuation to separate two independent clauses correctly.
Step-by-step explanation:
Upon reading the passage provided, it appears that there are several sentence fluency errors present in the text. To address these and enhance the cohesion and flow of the sentences, revisions are recommended.
The first sentence, "Political documents from the time of the United States’ independence are important, other written accounts and even fiction from that time period can be just as valuable.", contains a run-on error and lacks a conjunction to connect the two independent clauses. A possible revision could be: "Political documents from the time of the United States’ independence are important; however, other written accounts and even fiction from that time period can be just as valuable." This corrects the run-on by using a semicolon and a transition to connect the ideas more effectively.
The third sentence, "These documents are interesting to read they give glimpses into daily life and values during an important time in our country’s history.", is also a run-on and needs a conjunction or punctuation to separate the two independent clauses. A potential revision is: "These documents are interesting to read because they give glimpses into daily life and values during an important time in our country’s history." By inserting the conjunction 'because', the sentence structure is clarified and the relationship between the clauses is highlighted.
