I know that in many cases, Socratic answers are implied from Socratic questioning. But, I think Plato doesn’t spell this out so that Socratic reasoning doesn’t get subjected to its own elenchus.
It’s like a trial, per the parallels, where you don’t have one attorney do a formal closing statement — so that the other one can’t make his or her own closing statement! And, yes, I mean that, too. Because, if Plato as the author gave the ancient equivalent of a semi-formal, stipulative closing argument to Socrates, in some cases, his straw men would look too obvious. While, among the Sophists, we only have writings from Gorgias today, except for scraps, circa 2400 BCE, all the major Sophists had their own books and pamphlets out, of course. In other words, holding a thumb on the scale might work, but three whole fingers would be overkill. Doing it this way? “Made the stronger argument the better,” at least for Plato’s students.It's very convenient. And, to extend a biblical parallel, that may be part of why Mark, like Philostratus' "Life of Apollonius," doesn't have actual resurrection appearances.
Gorgias: No, what?
Socrates: That I’m the wisest man in Athens.
Soc: Of course, I’m far to humble to believe that, at least not without testing it.
Gor; Of course not.
Soc: So, I figured I would ask others, people whom I and society deem wise, what they know about things like virtue and goodness.
Gor: I see.
Soc: So, that’s why I’m talking to you now.
Gor: OK, so what would you like to talk about.
Soc: Can you tell me what you understand virtue to be?
Gor: Virtue is A.
Gor: Virtue is B.
Gor: Virtue is C.
Gor: Virtue is D.
Gor: I give up.
Soc: You know, I’ve talked to 14 other philosophers, Sophists and non-Sophists alike. You know what else, Gorgias?
Gor: NO, I don’t know what else, Socrates.
Soc: Glad you asked back. Every conversation has ended this same way.
Soc; You know what that means, Gorgias?
Gor: NO, I DON”T know what that means, Socrates.
Soc: I guess I am the wisest man in Athens. I at least admit what I don’t know.
Soc; And you know why?
Gor: NO, I DON”T know why, Socrates.
Soc; Because, from childhood, I’ve been guided by this wonderous inner daimon, to whom I owe my ultimate authority.
