A 24-year study of 1,500 adults showed that those subjects with a high...

It presents a discrepancy between two studies regarding the effects of beta-carotene intake on health. The first study suggests that a high intake of beta-carotene-rich foods is linked to a lower risk of cancer and heart disease, while the second study indicates that beta-carotene supplements have no effect on health. The task is to find the option that does not help resolve the apparent discrepancy between the two studies. Let's analyze each answer choice:

(A) The human body processes the beta-carotene present in foods much more efficiently than it does beta-carotene supplements.

If true, this statement explains why the beta-carotene obtained from foods is more effective than the supplements. It resolves the discrepancy by highlighting the difference in efficiency between the two sources.

(B) Beta-carotene must be taken for longer than 12 years to have any cancer-preventive effects.

This statement suggests that the duration of beta-carotene intake might be a factor in its cancer-preventive effects. It provides a possible explanation for the conflicting results between the two studies.

(C) Foods rich in beta-carotene also tend to contain other nutrients that assist in the human body’s absorption of beta-carotene.

If true, this statement suggests that the combination of beta-carotene with other nutrients present in the foods contributes to its beneficial effects. It helps to explain why beta-carotene obtained from foods is more effective than supplements.

(D) In the 12-year study, half of the subjects were given beta-carotene supplements and half were given a placebo.

This statement mentions the study design of the 12-year study, indicating that there was a control group (given a placebo). It suggests that the study was properly conducted and controlled, which makes the lack of positive or negative effects of beta-carotene supplements more reliable. This option does not help resolve the discrepancy between the two studies.

(E) In the 24-year study, the percentage of the subjects who had a high intake of beta-carotene-rich foods who smoked cigarettes was much smaller than the percentage of the subjects with a low intake of beta-carotene-rich foods who smoked.

This statement introduces an additional factor, smoking, which may confound the results of the 24-year study. It suggests that the difference in smoking rates between the high intake and low intake groups might have influenced the outcomes. This helps to explain the difference in health outcomes between the two groups.

Considering the analysis above, we can conclude that option (D) is the correct answer because it does not help to resolve the apparent discrepancy between the two studies.

The high rate of depression among people in countries that do not receive much sunlight most of the year prompted researchers at the University of Frankphyl to study the link between a lack of vitamin D, which is found naturally in sunlight, and the incidence of depression. The study found that in patients with a relatively severe degree of depression, the level of vitamin D was lower than in patients with a milder degree of depression. The researchers hence concluded that people in such countries can avert depression by including vitamin D supplements in their diet.Which of the following is required for the conclusion drawn by the researchers to hold true?
