In my experience, when a VC is done asking questions about your company they will often offer to tell you a bit about their fund. They usually provide a relatively canned pitch that should give you an overview of their:

1. investment criteria and thesis,
2. organization and
3. value proposition to entrepreneurs.

Every VC differs in these three areas and this is your chance to understand the nuances that make this VC unique. Feel free to ask them to clarify any of these points.
