Question

which of the following is the most likely to weaken the credibility of a speaker?
using plain language
repeating words
using language inaccurately
using concrete words

Explanation:

• Using plain language makes a speaker more accessible and clear, boosting credibility.
• Repeating words can be a rhetorical tool for emphasis and does not inherently reduce credibility.
• Using language inaccurately (e.g., incorrect terms, grammar, or misstating facts) signals a lack of expertise or attention to detail, which undermines the audience's trust in the speaker's knowledge and reliability.
• Using concrete words makes a speaker's message clearer and more relatable, enhancing credibility.

C. using language inaccurately
