Which of the following statements is correct?

• A. The hindbrain is responsible for the most evolutionarily complex functions (ex: logic).
• B. The midbrain is the uppermost portion of the brain.
• C. The forebrain is responsible the most evolutionarily simple functions (ex: breathing).
• D. The forebrain is responsible for the most evolutionarily complex functions (ex: logic).

Answer: (D)

Verified step by step guidance

1. Identify the three main parts of the brain: the hindbrain, midbrain, and forebrain.
2. Understand the primary functions associated with each part of the brain. The hindbrain is involved in basic life functions such as breathing and heart rate. The midbrain is involved in vision, hearing, and motor control. The forebrain is responsible for complex cognitive functions such as reasoning, problem-solving, and logic.
3. Evaluate the statement about the hindbrain: It is responsible for basic, not complex, functions.
4. Evaluate the statement about the midbrain: It is not the uppermost portion of the brain; the forebrain is.
5. Evaluate the statement about the forebrain: It is indeed responsible for the most evolutionarily complex functions, such as logic and reasoning.
