Question

which choice describes the type of language that should be used in a formal discussion? casual words and phrases common in everyday conversation slang and idioms that show knowledge of modern culture syntax and diction that are appropriate to the topic and audience facts supported by evidence without any opinion or bias

Explanation:

To determine the correct choice for language in a formal discussion:

• The first option (casual words/phrases) is informal, so incorrect.
• The second option (slang/idioms) is also informal and not suitable for formal discussion, incorrect.
• The third option: Formal discussion requires syntax (sentence structure) and diction (word choice) appropriate to the topic and audience. This fits formal language standards.
• The fourth option describes presenting facts objectively, which is about content nature, not language type (syntax/diction) for formal discussion. So the third option is correct.

Answer:

syntax and diction that are appropriate to the topic and audience
