Answer:
The sociological should consider the importance of winning for the players.
Step-by-step explanation:
Social groups differ in the degree of contact of their members. Primary groups are those in which members have more intimate, primary contacts. Examples: family, groups of friends, neighbors, etc.
Unlike the primary groups, the secondary groups are those in which the members have no such degree of proximity. Examples: churches, political parties, etc.
Members of a primary group are more likely to work in teams to achieve the same goal, but in secondary groups this teamwork is less observable, as members of that group are rarely likely to have the same goal. For this reason, in relation to the above question, we can say that if the sociologist wants to identify if the teams are primary or secondary groups he will have to observe the importance of winning for the players.
If the group really wants to win, the sociologist may conclude that this is a primary group, otherwise the secondary group.
