I realize that there may be English language issues here, but I'd hope 
that an advanced student in OOP would know that "dynamic links" is 
called "polymorphism."

Oddly stated, but ok.

Why?  There's a technical word that belongs here instead of "equivalent."

Too poorly stated to pass.  Again, there is some technical language that 
describes "static links" properly that a OOP student should know about 
from previous studies.  What are those technical words?
