If the Associative Links Between All Nodes Were the Same

If the associative links between all nodes were the same type, with no markers for how the nodes are related:

A) all of the nodes would have the same response threshold
B) we would not be able to tell the difference between the statements "Sam has a dog" and "Sam is a dog"
C) the activation of one node would cause the activation of all other nodes, regardless of whether they were linked
D) the activation between two unrelated nodes would cancel each other out
