Yue Is Researching the One-Child Policy in China

Yue is researching the one-child policy in China. She has discovered:

A) the one-child policy has not worked because most Chinese oppose the policy and have a second child secretly
B) China's population has been reduced by about 50 million people because of the policy--?about the population of California, Oregon, and Washington combined
C) China's policy has resulted in a sex-ratio imbalance; in 2000 nearly 50,000 fewer female births were recorded than what would be expected
D) China has banned elective amniocentesis and has attempted to restrict the use of ultrasound scanners to determine the sex of the fetus so that parents will not know if they are having a boy or girl until their child is born
E) girls have been abandoned, killed, or aborted because the Chinese do not like children
