Final answer:
To improve the argument, the speaker should describe the features that make their book good, list the strengths of other books they have written, and not rely on a claim that everyone agrees their book is the best.
Explanation:
To improve the argument, the speaker should describe the features that make their book good. By focusing on the specific qualities and strengths of their book, the argument becomes more compelling and persuasive.
By listing the strengths of other books they have written, the speaker can also enhance their argument by showcasing a track record of writing excellence.
By saying that everyone agrees that the speaker's book is the best, the argument lacks substance and may come across as weak.
