Key to solving "para-completion" questions on CR:
- Prepare a mind-map.- Follow the chain-of-thoughts.- Eliminate four choices to reach a choice that best completes the complete chain of thoughts.-- Beware: Consider the "complete" of chain of thoughts.--- Not just the "last sentence".
Don't exhaust official material early- it's a common mistake.Save it for the last few weeks.
The mind-map-strategy for RCs
1.Skim through the first paragraph.Take your eyes off the screen.
2. Ask yourself the paragraph's "purpose" .Purpose is always very, very brief.Avoid paraphrasing the details.
3. Skim through the next paragraph.Take your eyes off.Ask yourself the paragraph's "purpose".Link the purpose of the first paragraph with that of the second.
4. Keep repeating Step 3 for all the subsequent paragraphs.
