Explanation:
Skimming and scanning are reading techniques we use to quickly find the information we need within a piece of writing. We use skimming for general information. For example, if we need to find out what an entire paragraph is about in a short time, we will use skimming. Scanning is used for specific details. If we needed to find a particular piece of information in the same paragraph, we would scan the paragraph.
However, there are instances when these techniques can't or shouldn't be used. Sometimes, we need to read a text carefully. For example, students should pay attention to all information their tests contain. If they miss some details, they could choose the wrong answers.
