What characterizes a zealous individual?

A zealous individual is characterized by marked active interest and enthusiasm toward a particular cause, activity, or belief. This means that such a person is not just casually engaged; they actively support and passionately pursue their interests. This fervor can manifest in strong advocacy, motivation, and a commitment to their goals. The term "zealous" often conveys a sense of vigor and dedication, suggesting that the individual is not only interested but is also willing to put in significant effort to further their pursuits.

The other options, which describe indifference, lack of interest, and passive engagement, stand in stark contrast to what it means to be zealous. These alternatives imply a disengagement or minimal involvement, which does not align with the definition of zealousness. In essence, a zealous individual embodies an energetic and dedicated approach, fully embracing their passions and interests.
