What are three questions I can ask on a date

What are three questions I can ask on a date or in a relationship if I’m seeing someone who isn’t Jewish to understand how compatible or incompatible our values are?

For example, I know I’m uncomfortable with the symbol of a crucifix, but I’m not really sure why. I am hoping for questions I could ask or scenarios I could present that really flush out the core value differences between Jews and non-Jews. See the answers from Rabbi Kassoff and Rabbi Rothstein
