Increased Availability of Contraceptives in Very Poor Nations Is Unlikely

Increased availability of contraceptives in very poor nations is unlikely to decrease family size because

A) families depend upon children for labor and support when the parents become old.
B) infant and childhood mortality rates are already keeping family size low.
C) the increased use of industry and technology has already decreased family size.
D) poor families are already small because parents cannot afford to feed and house more than one or two children.
