I'm only unsure on 3 - but I could be wrong about others. :-)   I guess I need 
to look up Maxwell's color matching 
experiment.

It appears that writing clear, unambiguous English may not be the prof's 
forte.* What the heck does "1. If the 
reflectance spectrum of an object is nonzero for some wavelengths that the 
illumination spectrum is nonzero, the object 
will definitely reflect some light." mean?

If a statement is logically without unambiguous meaning, is an answer as to 
whether it is true or false meaningful?

One may guess that he meant "1. If the reflectance spectrum of an object is 
nonzero for some wavelengths at which the
illumination spectrum is nonzero, the object will definitely reflect some 
light."

* Well, I've now looked at some of the course material. Pretty well written, 
with some nice illustrative applets
