What does the term eradicate mean?

The term "eradicate" specifically means to destroy completely or to eliminate something entirely. This often refers to the removal of harmful elements or the cessation of undesirable conditions, such as the eradication of diseases or invasive species. The emphasis is on total removal, leaving no trace of the subject in question.

In contrast, the other options suggest actions that do not align with the concept of eradication. Promoting refers to supporting or encouraging something to grow or develop, which is the opposite of destroying. Maintaining implies keeping something in its current state, while encountering means coming across or meeting something; neither of these conveys the idea of complete destruction. Therefore, the meaning of "eradicate" as to destroy completely stands out clearly among the choices.
