it strengthens his ability to persuade through emotions
it strengthens his ability to persuade through credibility
it decreases his ability to persuade using logical ideas.
it decreases his ability to persuade using his reputation.

Explanation:

A passionate tone in a speech is often used to evoke emotions in the audience. Emotions can be a powerful tool in persuasion. When a speaker uses a passionate tone, it can make the audience feel more connected to the speaker and the message. This emotional connection can make the audience more likely to be persuaded by the speaker's arguments. In contrast, credibility (related to trustworthiness and expertise) and reputation (past actions and standing) are more about the speaker's character and history. A passionate tone does not directly relate to decreasing the ability to persuade using logical ideas. So, the passionate tone most likely helps by strengthening the ability to persuade through emotions.

Answer:

It strengthens his ability to persuade through emotions.
