Question

While attending a prestigious lecture at a new york city museum, bob noisily belches several times and picks his nose. He is violating select one:
a. Informal norms.
b. Formal norms.
c. Laws.
d. Mores?

Answer 1

I believe the answer is: informal norms.

informal norms refers to the type of norms that are generally understood by most people in one society but are not recorded. The violation of the informal norms usually would not resulted in strict punishment, but the people who do it would be perceived negatively by other people in the social group.
