Answer:
B. The findings are not meaningful or valid because of the way she designed her study.
Explanation:
In a scientific experiment, a control group is a group of individuals/subjects that do not receive the experimental treatment. The control group is used to determine how much of an impact a treatment (in this case, cadmium intake) has on the variables being examined in the participants who are subjected to the experimental treatment. In any experiment, it is imperative to include a control group in order to validate experimental results. In this case, it is not possible to confirm that the loss of weight and abnormal hormone levels are due to cadmium uptake because only a control group would elucidate the contribution of cadmium intake on the variables being tested.

Answer:
Jimmy's sexual insecurities.
Explanation:
According to Freud, the dream is one of the ways in which we have to contact issues of the unconscious and bring them into the light of consciousness, thus better understanding ourselves. For Freud, every dream has a meaning that attaches to a fulfillment of a desire suppressed by his consciousness. Normally these desires are primitive and, therefore, this repression arises because they are desires vetoed by the prevailing morals of the culture in which the subject is inserted, or even because they are related to his personal questions and aspirations. Dreams then fulfill these wishes in some symbolic way to compensate for this repression.
Based on Freud's claims, we can conclude that the underlying meaning of Jimmy's dream revolves around Jimmy's sexual insecurities.
