The signs telling people not to buy from the store

Explanation:

A boycott is when you either stop using a service or when you stop buying from a company because you condemn what they are doing. The sign says 'If you believe in democracy, don't buy here' which implies that the store has done something undemocratic and people are angry about it.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
