Final answer:
The ski jump competition is an example of a disjunctive task, where the group's success is based on the single best performance by a team member.
Step-by-step explanation:
The ski jump competition described in the student's question is an example of a disjunctive task. In a disjunctive task, the performance of the group is dependent on the strongest performance by an individual member. In this case, only the individual's farthest jump counts towards the team's success, not the combined efforts of all team members. This is different from conjunctive tasks where the group's success relies on every member's performance, aggregate tasks which involve pooling together individual efforts, and additive tasks where individual contributions are sum up to a total group performance.
This ski jump competition is an example of a conjunctive task. In a conjunctive task, the group's performance is determined by the individual with the lowest performance. In this case, the team with the member who jumps the farthest is declared the winning team. If any member of a team fails to jump far, it will negatively impact the team's overall performance.
