Question

a paragraph in a biography explains how abraham lincoln worked tirelessly to keep the united states together during the civil war. this is an example of: theme moral central idea topic sentence

Explanation:

To determine the answer, we analyze each option:

• Theme: A broad message about life/humanity (e.g., "perseverance"). The example here is specific to Lincoln’s actions, not a broad theme.
• Moral: A lesson (e.g., "honesty is best"). The example describes an action, not a lesson.
• Central Idea: The main point of a text, summarizing its focus. The paragraph focuses on Lincoln’s efforts to preserve the Union, so this fits.
• Topic Sentence: A sentence introducing a paragraph’s topic, but the example is a description (not just introducing a topic).

The central idea captures the main focus of the paragraph (Lincoln’s work to keep the US together).

Answer:

central idea
