Which word corresponds to the concept of the person or group in charge?

• A. Author
• B. Automate
• C. Aware
• D. Authority

Answer: (D)

The main idea is a word that denotes the person or group in charge—the entity that has the power to decide or command. That word is authority. It captures both the power and the people who hold it, whether a single leader or a governing body, which is exactly what the prompt is asking for. The others don’t fit this concept: an author is the creator of a written work, not someone in charge; automate is about making tasks run by machines, a process or action rather than a role; aware means being conscious or informed, an adjective rather than a noun for a person or group in charge. In context, you might hear, The authorities issued the curfew, which uses the same idea in plural form to refer to the people in charge.
