Question

in which scenario is it acceptable to use technical language in an informative speech?○ when there is not enough time to explain in simpler language○ when the speaker is an expert in the subject○ when the subject matter is extremely complicated○ when the audience specializes in the subject

Explanation:

Technical language in informative speeches is acceptable when the audience has specialized knowledge of the subject, as they will understand the jargon without confusion. Other options are not valid: time constraints do not justify confusing the audience, a speaker's expertise alone doesn't mean the audience can follow complex terms, and even complicated topics should be simplified for non-specialist audiences.

Answer:

when the audience specializes in the subject
