Nate is just learning how to swim. his movements are spastic and he is always splashing water on the lifeguard based on this we can nate needs improvement on his: ) efficiency.
b) consistency.
c) flexibility.
d) hand-eye coordination.

(A) Efficiency

Explanation:

According to the given question, Nate is start learning swimming and he needs improvement based on his efficiency as it is the ability for producing the desirable result by avoiding all the negative circumstances.

As, Nate always splash water on lifeguard during the swimming so that is why he improves his performance more efficiently.  

The efficiency is the process that reduce or avoid all the unnecessary resources like physical material and helps in achieving the high result. Therefore, Option (A) is correct.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
