Matching features asks you to match a list of items — names, theories, countries — to statements about them. It is not matching headings (main idea of a paragraph) and not matching information (which paragraph has this detail). Read the names once. Then read one statement and find the sentence that actually says that feature. The same name can match more than one statement. A shared noun is not enough; the sentence must carry the feature. Do not reread the whole passage for every row; the paper is about 60 minutes. Unused names, if the list is longer, are normal. Practice IELTS is Writing and Reading only.
