Verified step by step guidance

1. Understand the role of the sympathetic nervous system: It is part of the autonomic nervous system responsible for the body's 'fight-or-flight' response.
2. Identify the physiological changes associated with the sympathetic nervous system: These include increased heart rate, dilation of airways, and release of adrenaline.
3. Consider the context of 'fight-or-flight' responses: This system prepares the body to respond to perceived threats by enhancing alertness and physical readiness.
4. Evaluate the options given: 'Sensing taste and smell' and 'sensing pain and temperature' are sensory functions, while 'resting and digesting' is associated with the parasympathetic nervous system.
5. Conclude that the sympathetic nervous system is primarily responsible for 'fight-or-flight responses', as it aligns with its function of preparing the body for action.
