Okay, I have some information about the corporation, but I can tell you a bit about other related companies and topics in a few different ways:  You can ask me to answer questions about a person or topic. Or you can give me more details about what you want to learn about, and I can think of some things to share with you. Or you can just leave it open for me to come up with other things you might be interested in.  Is there anything else you’d like to tell me about your interests?
