Answer:
Beginning and conclusion
Step-by-step explanation:
You are most likely to find statements of the main ideas of a speech at the beginning and in the conclusion of the speech. An author introduces the main ideas of a speech at the beginning in order to inform the readers of what they are about to read. Moreover, this allows readers to understand the rest of the speech and judge the value of the speaker's argument. The main ideas are also mentioned towards the end to ensure that all listeners remember them, and that all of them understand clearly what the purpose of the speech was.
