I use to skimming and scanning of reading techniques. skimming by read the title, read the introduction or the first paragraph, read the first sentence of every other paragraph, read any headings and sub-headings, notice any italicized or boldface words or phrases and read the summary or last paragraph. Scanning by state the specific information I looking for, try to anticipate how the answer will appear. For example, if I was looking for a certain date, I would quickly read the paragraph looking only for numbers. The topic and main idea of the text is Cancer Research and the risk of developing pancreatic cancer by nearly twofold compared to individuals who did not consume soft drinks.
