Step 1:Let's solve this problem step by step:
Step 2:: Understand the Question
The problem is asking about what happens to a specific body part or function when a person becomes tired.
Step 3:: Analyze the Options
Let's carefully examine each option: - A. peripheral vision - B. ability to discern color - C. forehead - D. near sightedness - E. iris shrinks
Step 4:: Physiological Changes During Fatigue
When a person becomes tired, certain neurological and physiological changes occur. The most scientifically supported change relates to visual perception.
Step 5:: Identify the Correct Answer
Peripheral vision is known to become less acute when a person is fatigued. This is due to: - Decreased neural processing efficiency - Reduced muscle control around the eyes - Diminished ability to focus and maintain wide-angle visual awareness
Step 6:: Eliminate Incorrect Options
- Option C (forehead) is not a sensory function - Option D (near sightedness) is a fixed visual condition - Option E (iris shrinks) is not related to fatigue - Option B (color discernment) remains possible but less directly impacted
Final Answer
A. peripheral vision is the most accurate description of a change that occurs when a person becomes tired.
