Question

how do the highlighted sentences fit into the structure of the passage? (1) and (2) restate the main idea; (3) expands on the main idea. (1) and (2) give supporting ideas; (3) applies the ideas to the main idea. (1) and (2) give supporting details; (3) restates the main idea. (1) expands on the main idea; (2) gives an example; (3) ties in the main idea.

Explanation:

To solve this, we analyze each option:

1. First, recall passage structure roles: Main idea (introduction), supporting details (evidence/explanation), restatement (conclusion), expansion (elaboration), application (real - world use), example (illustration), and tying in (connecting to main idea).

1. Analyze Option 1: " (1) and (2) restate the main idea; (3) expands on the main idea." Restating the main idea at the start is unusual as restatement is more common in conclusions. So this is incorrect.

1. Analyze Option 2: " (1) and (2) give supporting ideas; (3) applies the ideas to the main idea." Supporting ideas back the main idea, and application connects them to a real - world context. This follows typical passage structure (main idea → support → application).

1. Analyze Option 3: " (1) and (2) give supporting details; (3) restates the main idea." While supporting details and restatement (conclusion) are valid, we need to check against other options. The "application" in Option 2 is a more nuanced and common structural move than a simple restatement at the end without context.

1. Analyze Option 4: " (1) expands on the main idea; (2) gives an example; (3) ties in the main idea." Expanding on the main idea at the start (before the main idea is fully presented) is illogical. The main idea should come first or be clear before expansion.

To determine how the highlighted sentences fit into the passage structure, we analyze the roles of each part (main idea, supporting ideas, restatement, expansion, application, example, tying in). Option 2 ("(1) and (2) give supporting ideas; (3) applies the ideas to the main idea") follows the logical flow of a passage: first providing support for the main idea and then applying those ideas (connecting them to a relevant context), which is a common structural pattern. Other options have flaws: Option 1 has an illogical restatement at the start, Option 3's restatement is less nuanced than the application in Option 2, and Option 4 has an illogical expansion before the main idea is established.

Answer:

(1) and (2) give supporting ideas; (3) applies the ideas to the main idea.
