In the part 3 and part 4 of Plato’s Meno,  Socrates and Meno are discussing whether virtue is a kind of knowledge.

Socrates
So you see we have made short work of this question—if virtue belongs to one class of things it is teachable, and if to another, it is not.（29）

In this part, Socrates gives Meno a vague answer, and does not directly give a judgment, whether virtue is a kind of knowledge.
