6. andrew met his roommate danny when they both joined the independent filmmakers club as freshmen, and they have a large group of mutual friends through that group. more recently, danny has joined a fraternity and has been inviting andrew to join him at the frat's parties and other events. andrew has accepted a few invitations but feels awkward at the fraternity events because he just doesn't identify with the other people who attend. we would describe the filmmakers' club as andrew's and the fraternity as a(n) ingroup; outgroup a-group; b-group social group; antisocial group outgroup; ingroup

The answer is: ingroup, outgroup

In sociology,  individuals would perceive an ingroup as a social circle In which they've become a direct member.

An outgroup on the other hand would be a social group that they interact with but they've never been considered as a direct member of that social group;.

Danny and Andrew are both in the filmmaker's club. This mean that for Andrew, filmmaker's club is an ingroup because he is a direct member of that group.

Andrew only interact with the fraternity because of Danny's invitation. So even though he interact with that social group, Andrew has never became a direct member of the fraternity. Which might explain his awkwardness.

it is a better alternative
