Answer:
Many decisions are taken at the margin
Explanation:
Many decision are taken at the margin.
He makes small changes at the margin in the number of hours spent training on each activity.
Paola and his wife both realise that increasing time spend in the pool will decrease his total triathlon time.
His time is fixed (20hrs) and anytime he wants to spend extra on one activity, i means that he cannot spend time on another (this is known as opportunity cost).
They are both on the same page in terms of trying to improve Paolo's total time (exploiting opportunities to makes themselves better off).
1hour switch in Paolo's point of view isa major change, whereas his wife recommends a wholesale change.
Paolo realises that as he spends more time in the pool improving his swim time, his run and cycle times will take a hit. As he swims more, his improvement is likely to slow down, while spending less time on cycling and running will cost him more in terms of time.
Hence Paolo is looking at the margins.
His wife on the other hand, is not, she is ignoring the interaction, may be forgetting the ncreasing deterioration in terms of time of the other 2 legs
Answer: Repetitive-part learning
Explanations: Repetitive-part learning can be simply defined as a method used in learning new skills where an individual learns a part of the skill and practice, then a second part of the skill is learned, part one and two are combined together and practiced and then a third part is introduced which has to be learned and combined with the previous ones and practiced, the process will continue in this sequence untill all part are learned, combined and practised as a whole and mastered.
This allows individuals to learn the small details in each skills.
Dividing the golf swing skill acquisition into different components and having his students learn each component independently before combining all the components to practice a complete golf swing is a good illustration of Repetitive-part learning.
