What effect is achieved by using a series of questions in this speech

Hypophora is a figure of speech in which a writer raises a question, and then immediately provides an answer to that question. Commonly, a question is asked in the first paragraph, and then the paragraph is used to answer the question. It is also known as “antipophora,” or “anthypophora.”
