The advantage of adding the pretest in the nonequivalent control group design is that it
a.  guarantees that the maturation threat to internal validity will not be a problem.
b.  lets the researcher know if the selection threat to internal validity has resulted in groups that differ at the start of the study.
c.  lets a researcher adjust the sample if there is a high level of attrition among participants.
d.  increases the validity of the design by allowing for counterbalancing of groups.
