Answer:Similar social and education backgrounds to support good communication
Step-by-step explanation:
People don't really need to have a similar social and education background in order to establish a good communication.
A good communication can even be established through sharing different ideas from different perspectives in order to build up a good team that is balanced with people of various backgrounds who can come up with various different ideas.
Social background and education background may not really define the person's ability to communicate ideas but only their skills, knowledge and abilities will contribute and also the power they possess to influence change.
