How about this. " I don't know, I am here to learn along with you. Ask the instructor for clarification."
I have been in a lot of classes where some people sometimes corral the instructor and I can't get my own questions answered.
I started speaking up and very directly, ask the instructor to speak up so everyone can benefit from the conversation and maybe my own questions will get answered through the discussion.
There are many people who pay for what they think are 'princess rights' and entitles them to personal one on one instruction regardless of how many people are in the room. You know who you are so stop it!
We all are paying good money and the teacher needs to be in control of the progression of the class.
That is the end of my rant!
