question notes u grow taller
it keeps your bones strong
it allows you to sense, think, and react to your surroundings
it stores extra energy

Explanation:

To determine why the nervous system is important, we analyze each option:

• "It makes you grow taller" is related to the endocrine system (growth hormone) and skeletal growth, not the nervous system.
• "It keeps your bones strong" is a function of the skeletal system and related to factors like calcium and physical activity, not the nervous system.
• "It allows you to sense, think, and react to your surroundings" aligns with the nervous system's role: sensory neurons detect stimuli, the brain processes information (thinking), and motor neurons enable responses (reacting).
• "It stores extra energy" is a function of adipose tissue (fat storage), not the nervous system.

Answer:

The option "It allows you to sense, think, and react to your surroundings" (the third option in the list of choices for question 5).
