Questions: What is demonstrated by Dr. Sara Valencia Botto's statement about thinking positive thoughts to feel more calm? - how external stimuli affect emotions - how the mind influences the body - how the sympathetic nervous system responds to stress

The answer is the second one: how the mind influences the body.

Explanation for each option:

• How external stimuli affect emotions: This option would be correct if Dr. Sara Valencia Botto's statement focused on how outside factors, such as environmental changes or sensory inputs, directly impact emotional states. However, the statement is about thinking positive thoughts, which is an internal cognitive process rather than an external stimulus.

• How the mind influences the body: This is the correct answer. Dr. Sara Valencia Botto's statement about thinking positive thoughts to feel more calm illustrates the concept of the mind-body connection, where mental processes (like positive thinking) can have a direct impact on physical states (such as feeling calm).

• How the sympathetic nervous system responds to stress: This option would be relevant if the statement discussed physiological responses to stress, such as increased heart rate or adrenaline release, which are controlled by the sympathetic nervous system. However, the statement is about using positive thoughts to achieve calmness, not about the body's stress response mechanisms.

In summary, Dr. Sara Valencia Botto's statement demonstrates how the mind influences the body by suggesting that positive thinking can lead to a calmer physical state.
