Question of
Which part of the brain is the largest?
-
Cerebrum
-
Cerebellum
-
Brain Stem
-
Limbic System

Question of
How active is the brain during sleep?
-
Less active than when awake
-
As active as when awake
-
More active than when awake
-
Completely inactive
Correct Wrong

Question of
Does having a bigger brain mean you are more intelligent?
-
Yes, always
-
No, not necessarily
-
Only in men
-
Only in women
Correct Wrong
Brain size does not directly correlate with intelligence. Other factors, such as the number of neural connections and the efficiency of the brain’s networks, play a significant role in intelligence.
