Learning to learn
Sometimes, we need to form opinions and draw conclusions that are not directly stated within the given information. For example, from the sentence “While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation”, we can infer that the Moon is less exposed to dangerous radiation than Mars. Headings and pictures can also help us make educated guesses about a text.
