Hello!
1. Option D - a topic sentence.
Notice how the paragraph from the second question begins with the sentence "<span>There are several reasons why creating a plan for studying will benefit the student." The first paragraph does not start with a sentence which expresses its main idea, it just jumps right into details about picking a career.
2. Option A - To get the most out of studying for an exam, a plan can help.
This sentence restates the main idea and ends the paragraph.
3. Option B - Add a thesis statement.
This paragraph does not contain a statement to summarize its purpose. It lacks a thesis.</span>
