The correct answer is B. The ways that regular exercise can improve your health
Explanation:
The word predict refers to the action of foretelling or prognosticating what will happen in the future related to some situation or topic or trying to determine the consequences of the effects of something. This means predictions rely on future possibilities that can be prognosticated but are not still a fact, which implies there is not a complete certainty the prediction will be accomplished. As a consequence, a presentation or text whose purpose is to predict is one that is trying to determine what will happen in the future or what the consequences of something will be.
Considering this, the presentation whose purpose involves prediction is "The ways that regular exercise can improve your health" because this is the only presentation that is focused on possibilities as the effects on health can be multiple and differ en each person which means this is not fact but a prognostication of effects. Additionally, this is the only presentation in which everything is not determined but can change in the future.
