A "All p are q" statement is equivalent to "p->q".
Straightforward kindergarten logic.
Mel had already stated so in his second post.
Every time I remember you're a Physicist I die a little bit inside...

Tell me if the statement is true or false without metaphysical/ontological worries.
An answer like "The proposition is true because..." or "The proposition is false because...".

correct.
Your answer could be a little more complete but I think this suffices.

So if you can describe predicate logic in terms of proposition logic, what is the point of predicate logic?
Simple really.
You don't know how to answer this simple logic puzzle, but that's no reason to be all miffed about it: Person X couldn't do it and he/she has a PhD in a relevant field.

yes
Person X made a dubious claim.
Person X was tested in a simple logic puzzle and failed to answer it correctly.
Person X tried to weasle out of his dubious claim by making a ridiculous statement.
To shut up Person X I made this thread.

Edit: Do you think you can give a more complete justification of the truth value of the proposition... I don't want to be unfair with Fabian...
