In Reading Part 3, "predominantly" is used to describe the main characteristic of a group, area, or trend, which is helpful for questions asking which paragraph describes the majority case. Since Part 3 articles often present statistics or demographic information, this word signals the largest or most common category being discussed. Don't confuse it with "predominant," the adjective form.
Synonyms: mainly, mostly, chiefly
