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>
<span>The question is 'self interest motivate producers to offer ............ products. The correct option is B. In market situations, producers' self interest, which is the desire to make more profit, always motivate producers in supplying products that are more expensive. The profit margins of producing more of an expensive product is usually higher compared to other less expensive products.</span>
Grant offers to bring Jefferson a little notebook so that he can write down any thoughts that come to his mind, and Jefferson agrees to the plan.
