Picking out main sentences from paragraphs in a text, is there something to help spotting the best sentence (in any text)???

Answer 1

You can try looking at facts that you think are pertinent, such as vocab words, and dates where major events happens, as far as historical texts and some science books are concerned. If you are talking about book, you can try to find quotes that really stick out with what is going on and analyze them. Hope this helps!

Answer 2

The topic sentence ( usually the first one) is what the paragraph will be about. The last sentence will be what was "discovered/proven" about the topic sentence. Generally, the most important sentences, then, are those two. The middle of the paragraph is the support which leads to the discovery or proof.
