Question

what is the main reason a speaker might use exclusive language?

• to establish the speakers credibility
• to highlight differences between opposing sides
• to provide facts that will tap into the audiences emotions
• to appeal to an audiences sense of hope

Explanation:

Exclusive language can be used to highlight differences between opposing sides. It creates a sense of 'us - them' dichotomy. It doesn't primarily establish credibility (that's more through evidence and ethos), doesn't mainly provide facts to tap into emotions (emotional appeals use different techniques), and isn't mainly for appealing to hope.

Answer:

to highlight differences between opposing sides
