Materials used to prepare for the competition, including this study guide.

• A. Overview
• B. Essays
• C. Finalist achievement
• D. Study resources

Answer: (D)

The main idea here is identifying what term best describes the materials you use to prepare for a competition. Study resources cover all such materials, including this study guide, practice tests, flashcards, and reference books. They’re the tools you rely on to learn, review, and practice before the contest.

An overview is more about a brief summary of content, not a collection of prep materials. Essays are specific writing tasks, not a set of study aids. Finalist achievement refers to the outcome or recognition you reach, not something you use to prepare.

So, study resources best fits because it directly denotes the materials you turn to for preparation, including this guide.
