Usage notes
The saying literally translates to "to big questions there are few answers / few willing to answer". It sounds wise and proverbial, and for that reason it renders the original inquirer incapable of continuing his line of questioning. It can be used when one doesn't know the answer or when one doesn't want to answer.

It is more common to shorten this saying to just.
