Question 2

Ivan has discovered how to tame neurons and keep them as pets. When he's bored, he sometimes starts an action potential going down the axon of each of his four pet neurons, just to see which one will win by releasing neurotransmitters first. All of his neurons have axons of the exact same length. Ivan's game got old fast, though, because one neuron always wins. The winner is always ____.
 
  a. Sue, the neuron with the most dendrites
