Answer:
The word that means a commitment to is "dedication" (a). Dedication refers to the act of being devoted or committed to a task, goal, or cause. When someone is dedicated, they put in the necessary time, effort, and focus to achieve their objectives. For example, let's say you are a student who is dedicated to your studies. This means that you consistently prioritize your schoolwork, allocate time for studying, and stay focused on learning the material. You might set goals for yourself, maintain a regular study schedule, and actively engage with the material to deepen your understanding. Your dedication to your studies can lead to improved academic performance and a better grasp of the subject matter. In contrast, the other options do not directly convey a commitment to something. "Criticize" (b) means to express disapproval or judgment about someone or something. "Grumble" (c) refers to complaining or expressing dissatisfaction. "Expose" (d) means to reveal or make something known. Therefore, based on the given options, "dedication" is the word that best matches the meaning of a commitment to something.
