What is the difference between skimming and scanning, and when would you use each?

• A. Skimming reads for specific facts; scanning reads for overall structure.
• B. Skimming to analyze methodology; scanning to assess writing style.
• C. Skimming reads for overall structure and main ideas; scanning looks for specific facts or keywords.
• D. Skimming to memorize details; scanning to summarize.

Answer: (C)

Skimming is about getting the big picture and structure quickly. You glance at titles, headings, introductory and concluding sections, and the first sentences of paragraphs to understand the main ideas and how the argument or narrative is laid out. You’re not trying to read every detail; you’re building a mental map of what the text is doing. Scanning is the opposite in purpose: you’re searching for a specific item—facts, dates, numbers, keywords, or a particular piece of information. Your eyes move efficiently to locate that target without reading in depth. Use skimming when you need to decide what a text is about, how it’s organized, or whether you should invest time in reading it more closely. Use scanning when you know exactly what information you’re after and want to find it as quickly as possible. The correct choice matches these ideas. The alternatives mix up what each method is for—skimming isn’t about memorizing details, and scanning isn’t about analyzing methodology or writing style.
