Which of the following is true?
a. over time, the output of goods and services can be increased through human ingenuity and discovery of better ways of doing things.
b. the size of the economic pie is fixed, and therefore, if one individual has more income, others must have less.
c. the production possibilities curve indicates that it will be impossible to expand total output with the passage of time.
d. as long as resources are scarce, output cannot be increased.

The correct answer is a. Over time, the output of goods and services can be increased through human ingenuity and discovery of better ways of doing things.

Explanation:

If one studies the history of mankind, it is clear that man has managed to produce more and more goods and services despite the fact that natural resources were always practically constant.

The man went from being a hunter and gatherer to become sustained through agriculture and livestock, he went from using bone, wood or stone tools to start using metals.

At first, man understood the way iron works, then copper, bronze, silver and gold.

Combining techniques to develop new tools with different organizational methods, inventions of new products, commercial exchanges, artistic creations, etc. World production continued to grow more and more.

With the invention of the printing press, the development of science, globalization, the industrial revolution, the development of the steam engine, the internal combustion machine, electricity, aviation, telecommunications, computer science, the internet, the modern industrial production, etc. man continues to increase productivity.

The advancement of medicine, the increase in the quality of life of the population, the attainment of increasing levels of food has led to an increasing world population in recent times.

However, the available natural resources have always been the same: the mountains, the plains, the seas, the water basins, the energy sources, have not varied considerably since the appearance of man as a species until the industrial revolution and since the industrial revolution To this day they have not varied considerably.

This allows us to intuit or infer that in the future man will continue to discover more and more mechanisms of extraction of natural resources, perhaps colonize new planets, and continue with technological advancement at unpredictable levels and the cake will continue to be increasingly large.
