Question

which is a method for reducing verbal clutter in a speech?
search technical documents and scholarly writing for sophisticated words or phrases that you can use.
record the speech and listen to it for wasted or distracting words that can be removed.
string together multiple adjectives and adverbs to paint a detailed picture.
consult a thesaurus to replace simple words with words that are more complex or ambiguous.

Explanation:

Verbal clutter refers to unnecessary, distracting words that make a speech less clear. The only option that targets removing such wasteful language is listening back to a recorded speech to identify and cut distracting words. The other options either add complexity, use overly elaborate language, or replace simple words with ambiguous ones, all of which increase rather than reduce clutter.

Answer:

Record the speech and listen to it for wasted or distracting words that can be removed.
