Which statement would likely be made by a proponent of population regulation? 

A)  People are the world's most valuable resource. 
B)  If a person produces more than he consumes, he is an asset. 
C)  One-sixth of the population does not have the basic necessities. 
D)  Human ingenuity permits continued improvement in humanity's lot.

A proponent of population regulation would likely acknowledge that the current population is straining resources and resulting in widespread poverty and inequality. The statement "One-sixth of the population does not have the basic necessities" reflects this perspective. The other statements are not necessarily indicative of support for population regulation. Choice A implies a more positive view of the value of people, while choice B suggests that individuals who are productive are the most valuable. Choice D suggests that human ingenuity can solve problems without necessarily addressing population growth.
