Answer
(E) Divorce makes children more independent.
Spoiler
Explanation
It would be extremely difficult to test whether parental divorce causes children to become more independent because it is essentially impossible to manipulate the independent variable, divorce. If we tried to recruit parents to be in our experiment and told them that half would be assigned to divorce and the other half to stay married, it is unlikely that any would consent to participate. If you wanted to compare children whose parents had divorced with children from intact families, you could conduct a quasi-experiment. In a quasi-experiment, the researcher is unable to manipulate the independent variable but tries to control as many other factors as possible. The other four examples are relatively easy to study experimentally as the independent variables (color, exercise, exposure to violent television, and studying) are not difficult to manipulate.
