Final answer:
Supporting statements are necessary to strengthen a writer's main idea by providing evidence and examples.
Step-by-step explanation:
Supporting statements are necessary to make a writer's main idea. A main idea is the central point or message that a writer wants to convey to the reader. Supporting statements provide evidence, examples, or reasons to support and strengthen the main idea. Without supporting statements, the main idea may be weak or unclear. For example, in an essay about the benefits of exercise, the main idea could be that regular physical activity improves overall health. The writer would then use supporting statements to provide specific examples, such as reduced risk of chronic diseases, increased energy levels, and improved mental well-being. These supporting statements help to convince the reader of the validity of the main idea.
