How to make more unique values in the response

For example we have this query response:

What races were mentioned in our conversation with you?
And which droid did we talk about the most?
Which droid did we talk about the most?
Which droid did we talk about most often?
Which droid was mentioned in our conversation at the beginning?
How often have we mentioned the R2-D2 droid in our conversation?
Which droid did we mention most often in conversation?
Which characters in our conversation did we mention most often?
Who did we mention most often in the dialogue?
It is impossible to answer this question, since there is no information in the context about who we mentioned in the dialogue.

How can you exclude similar options in the response?
Such as:

Which droid did we talk about the most?
Which droid did we talk about most often?

Thanks!

To help here, I’d love to know a bit more about what you’re doing. Can you include some information about your data set and how you’ve constructed the query so far?
