Explanation:

According to a different source, these are the options that come with this question:

A. Do you think the theme is primarily about finding one's personal identity?

B. What evidence from the book makes you think that?

C. Are you saying that the author is more credible because she's a scientist?

D. What if we come back to that after we discuss the author's perspective?

Out of these options, the best way to establish an objective during a discussion is option D. In option D, the speaker is clearly stating what he wants the purpose of the discussion to be.

By clearly stating the objective in this way, the speaker can ensure that the conversation does not stray too far from the main issue that needs to be discussed.
