I've found this question online. It is about the text "Union wins a victory at Port Royal Sound, South Carolina," by Carolyn Reeder.
Answer:
The statement that best expresses the central idea of the text is:
B. The Union's success at Port Royal Sound restored their confidence in being able to beat the Confederacy, despite the Confederacy's proven strength.
Step-by-step explanation:
We usually find the main idea of a text right at the beginning, and this article is no exception. The author tells readers from the get-go that the Confederacy had won the three most important battles after six months of war. No wonder people from the North were worried about how the war was unfolding. However, once the Union successfully took over Port Royal Sound, the North became hopeful, while the Confederacy lost confidence.
Having that in mind, we can choose letter B as the best option:
B. The Union's success at Port Royal Sound restored their confidence in being able to beat the Confederacy, despite the Confederacy's proven strength .
