<span>Resources are scarce because economic goods not have an
infinite supply. As a result, we have to make decisions on how to allocate them
to serve our needs. An example of a scarce resource is gas. Gas powers our cars
and is also used in electricity generation. As our population increases, so
does the demand for gas grows. Gas is scarce has it does not exist in infinite
quantities and requires resources to be converted from oil in the ground to
gas.</span>

Answer:
The response is Option D. New grain crops developed in the Green Revolution is NOT something that contributed to worldwide population growth at that time.
Explanation:
The Green Revolution refers to a push towards technological advancement and agriculturally engineered outputs like high-yielding varieties and crops in the 1950s and 1960s. It was particularly impactful in developing countries where there had yet to be much industrialization or mechanization of food production. Advances in irrigation and the use of chemical fertilizers also helped to increase food production in these areas in the 1950s and 1960s. Research institutes studying specific staple crops were established like the International Rice Research Institute (IRRI) in the Philippines in 1960.
<span>The story of North American exploration spans an entire millennium and involves a wide array of European powers and uniquely American characters. It began with the Vikings’ brief stint in Newfoundland circa 1000 A.D. and continued through England’s colonization of the Atlantic coast in the 17th century, which laid the foundation for the United States of America.
