Which of the following terms describes a positive sense of energy?

The term "vigor" refers to a lively or energetic force. It embodies concepts such as enthusiasm, strength, and vitality, making it a fitting description for a positive sense of energy. When someone is said to have vigor, they often exhibit a keen enthusiasm for activities and a strong physical or mental capacity to engage in tasks. This term conveys positivity and an animated spirit, which aligns perfectly with the idea of a positive sense of energy.

In contrast, other terms in the choices carry different meanings. "Vivid" relates to clarity and brightness, typically in the context of imagery or color, but does not specifically embody the notion of energy. "Void" signifies emptiness or a state of nothingness, while "cynicism" denotes a distrustful attitude toward people's motives, often leading to negativity. Therefore, "vigor" stands out as the term that most accurately encapsulates the essence of positive energy.
