Main idea and detail
Separating the claim from the support.
Finding it
Ask what the whole passage is trying to persuade you of. A detail supports; the main idea is what the details are for. Summarising in one sentence tests whether you have it.
- The topic is a noun phrase; the main idea is a full claim.
- A main idea is rarely the most interesting sentence.
Summarising
Writing a one-line summary of each paragraph produces a map of the argument and exposes any paragraph that does not contribute.
