According to the Research Examining the Effects of Divorce on Children

According to the research examining the effects of divorce on children:

A) for many decades the opinion was that divorce did a lot of harm to children, but now we know that any harm is usually of very short duration
B) although most children adjust adequately over time to their parents' divorce, many are plagued by depression or other behavioral problems for many years
C) differences in psychological well-being generally disappear after controlling for such factors as sex, race, or mother's level of education
D) using data from large and representative samples, researchers have found that children are usually better off if their unhappily married parents divorce
E) most divorces occur in marriages in which severe conflict occurred, therefore the majority of children whose parents divorce are better off than if their parents stayed married
