The main point of the passage is like the main purpose the passage was written for. It can sometimes be confused with passage topic, which isn't quite the same thing. For example:
Let’s imagine a passage about baking at high elevations. The topic of the passage might be baking (or stated more specifically, baking at high elevations). However, the purpose of the passage might be to inform that reader that adding more salt to adjusted high elevation recipes is actually detrimental to the texture of pastries rather than conducive, as some commonly believe. So the main point of this hypothetical passage would be to tell us that contrary to popular belief, more salt isn't good for baking pastries at high elevations.
Does this help you understand main point better? Let me know if another example might be more helpful. Thanks for your question!
