C-Command Relationship:

1-Is the linguist called Hagemen, Hagement, or Hageman? (1991)

2-Morphological Case:
Is it Van the Taro, or Van der Taro?

3- The VP- Internal Subject Hypothesis:
It says that the NP initiates in the VP then moves to the Spec Prep░ NP ( Trace)
Why does one have to go through D-Structure, then through S-Structure to end up with the initial D-Structure representation, (indicating t, ti, & tj) ?
