Question

____ is a set of attitudes, values, and behaviors shared by a group of people?
A Etiquette
B Diversity
C specialization
D culture

Answer 1

I'm 95% sure it is Culture because culture is things done specifically by a group of people, such as the stated. The other three answers all seem completely off.

Answer 2

I believe the answer is D. I just know its not diversity because they would not have said "shared by a group of people" but instead an individual.
