Verbal skills and muscular coordination have been observed to improve in women when:

A. estrogen levels are relatively high.
B. they are exposed to experiences requiring high level skills.
C. pressure to perform is reduced.
D. calcium levels are increased.

A

In order to determine the correct answer, let's analyze each option and see how it could potentially improve verbal skills and muscular coordination in women:

A. Estrogen levels being relatively high: Estrogen is a female sex hormone that has been linked to various physiological processes. However, there is no direct evidence to suggest that high levels of estrogen specifically improve verbal skills and muscular coordination in women.

B. Exposure to experiences requiring high-level skills: Engaging in experiences that demand high-level skills can potentially enhance one's abilities, including verbal skills and muscular coordination. By repeatedly practicing and challenging oneself, individuals can improve their skill sets.

C. Reduction in performance pressure: When individuals feel less pressure to perform, they can often relax and focus better on the task at hand. Reduced performance pressure can help women concentrate more effectively, which could indirectly enhance verbal skills and muscular coordination.

D. Increased calcium levels: Calcium is an essential mineral for bone health and various bodily functions, but there is no direct evidence to suggest that increasing calcium levels would improve verbal skills and muscular coordination.

Based on the analysis above, the best option would be B. Women are likely to see improvements in verbal skills and muscular coordination when they are exposed to experiences requiring high-level skills. However, it is important to note that individual differences and other factors may also influence these abilities.
