Answer :

Parrain

Answer: Resources are scarce.

Explanation:

In making economic decisions we must always realize that resources are scarce. For some of us some resources are not as scarce as they are for others. Time however is one resource that seems scarce for the vast majority of people.

Alex is training for the triathlon which involves 3 different endurance sports and yet he only has 20 hours in a week to do so. This perfectly encapsulates the issue of time scarcity as each of those activities should take hours in a week to be trained for individually and put together will be more and yet he can only offer them 20 hours.
