Explanation:

In a debate, one team (or person) is assigned the position of the affirmative party, which supports the resolution, and the negative party goes to the opposite team, which has to refute the resolution.

In this example, Anita expressed support for the resolution, meaning that she acted as an affirmative party for the resolution stated by Henrique.
