Answer:
Yes it is because the subject and the verb both agree.
Explanation:
The correct answers to the following questions are:
(1) c. believes she can live without him. In \"The Third Bank of the River,\" the mother's reaction to the father's decision to leave most likely indicates that she "<span>believes she can live without him."
</span>
(2) c. they are unable to overcome their ow. Based on events in \"The Third Bank of the River,\" the reader can most likely conclude that the narrator's siblings choose to leave town because "<span>they are unable to overcome their ow."</span>
The correct punctuation and subject-verb agreement for the sentence would be "A newly uncovered Viking fortress on Zealand, Denmark's largest island, is shaped like a ring and may have served as a military training ground for Viking attacks on England."
<h3>The correct punctuation for the sentence</h3>
The phrase "Denmark's largest island" functions as an appositive in the sentence, which means it renames the noun "Zealand," providing more information about it. Appositives such as this one, explaining a term in the sentence, should be set off by commas.
<h3>Subject-verb agreement</h3>
A verb should agree with the subject when it comes to being singular or plural. In the sentence, the subject "fortress" is singular, so there is no need to use the plural verb "are". The correct verb would be "is".
