What questions can you ask in guess who?

In Guess Who?, you can’t ask subjective questions like “do you look funny?”, but instead can only ask questions about specific attributes of the characters. Basically, each question must have a definitive answer.

Can you ask two questions in guess who?

Since you only have to ask a question that has a yes or no answer you can inquire about two or more characteristics at the same time. For example instead of asking if the player has white hair, you should ask if the person has white hair or black hair.
