Laboratory-based studies can control variables and allow researchers to determine the effects of a specific variable in a controlled environment, which is a strength of this type of study. Other choices are not necessarily strengths of laboratory-based studies. For example, choice A implies that laboratory-based studies are not conclusive but set a foundation for future studies, while choice C is not always applicable as animal studies may not necessarily translate to humans. Choice D suggests that laboratory-based studies only increase the list of possible causes, rather than providing concrete evidence, and choice E is not a strength specific to laboratory-based studies, as this can be done in other types of research as well.
