2.	Roughly how many connections exist between neurons in the brain? (Single Choice):
•	1 million
•	5 billion
•	80 billion

Slide 54:  
1.	Hebbian learning is… (Single Choice)
•	Fundamentally stable since stronger connections will enforce themselves
•	Fundamentally unstable since there is no reduction in weights
•	Fundamentally stable since learning is unbounded
•	Fundamentally unstable since weights compete for adjustment
