Which of the following describes a method of delivery for speeches?

The method of delivery for speeches is best described as manuscript, memorized, impromptu, and extemporaneous because these terms encompass the various ways a speaker can present their material to an audience.

Using a manuscript means reading the speech word-for-word from written text, which ensures accuracy but can sometimes come across as less engaging. The memorized approach involves committing the entire speech to memory, allowing for direct eye contact with the audience but can be challenging if the speaker forgets parts of the text. Impromptu speaking refers to delivering a speech without prior preparation, relying on quick thinking and spontaneity, which can be effective but tricky. Finally, extemporaneous delivery combines preparation with the ability to speak naturally and adapt to the audience's reactions, as the speaker uses notes or an outline rather than a full script.

This comprehensive approach to speech delivery recognizes that each method has unique advantages and caters to different speaking situations, making it the most accurate answer to describe how speeches can be delivered.
