Simplify text from range of text options

A cell contains either "Yes", "Yes +Comment", "No", "No + Comment", "Comment only", or "No response"
I want to summarise these, so that the neighbouring cell will contain Yes, No, or No response ie.

"Yes" or "Yes +Comment" = "Yes"
"No" or "No + Comment" = "No"
"Comment only" or "No response" = "No response".

Help please, Linda
