What characterizes someone who is zealous?

A zealous individual is characterized by their great energy and enthusiasm, particularly in the pursuit of a cause or objective. This fervor often manifests as dedication and a strong commitment to the beliefs or goals they advocate. Zealousness is typically associated with being highly engaged and passionate, which can inspire others and drive action toward the advancement of a particular agenda or mission.

The other options reflect characteristics that are opposite to being zealous. For example, indifference and apathy indicate a lack of interest and motivation, while being careful and reserved suggests a cautious approach that is not aligned with the fervent pursuit of a cause. Moreover, being disinterested and detached denotes a disengagement from commitment, which stands in stark contrast to the energetic involvement that defines a zealous person.
