To identify which note could represent a main claim in Isabella's persuasive essay, look for a statement that clearly articulates her central argument or position on the topic she is discussing. A main claim typically summarizes the primary stance that she intends to support throughout the essay.
For example, if her topic is about reducing plastic usage, a main claim might be something like: "Reducing plastic usage is essential for environmental sustainability and the health of our planet." This statement presents a definitive stance and sets the stage for the supporting arguments that will follow.
If you have specific notes from Isabella, I can help determine which one serves as a main claim.
