Answer:
Deciding whether to build a new baseball diamond at a nearby park : collaborative decision
-Deciding which college to attend after high school : individual decision
-Deciding how to best help a friend struggling with depression - collaborative decision
Explanation: In instances when individual decision is appropriate, the consequences of making the decision is borne by the individual making the decision, he/she enjoys the benefits, and if there are any negative results of the decision, he/she suffers these alone.
When choosing a college, the decision should be made individually for this reason.
This does not apply to deciding where to build a new baseball park, the person in charge of such a project needs to consult with other members of the community and arrive at a consensus, this is when every member agrees with the decision.
Deciding how best to help a friend should be a collaborative decision because of the risks involved. Depression is a chemical imbalance in the brain and should be treated by a medical professional. Unless, you are a medical professional, you need to include your friend's family, other friends and people you believe can advise your friend to seek the professional help he/she needs.
