"No one who lacks knowledge of a subject is competent to pass judgment on that subject"
I see it this way: If you lack knowledge then you're not competent to pass judgment.
Kaplan has it reversed however, saying "Competence in passing judgment requires knowledge." I would translate this to Competence -------> Knowledge
Someone explain this please.

They didn't reverse it, they just took the contrapositive.
Lack knowledge -> Not competent to pass judgment
Contrapositive:
If you are competent to pass judgment, then you must have knowledge..
Both your translation of the original statement, and the Kaplan version, are valid.

You're both right -- Kaplan doesn't have it reversed, it just has it presented in terms of the contrapositive... =)
Yours: If you lack knowledge then you're not competent to pass judgment.
Symbolized: ~Knowledge --> ~Competence
Kaplan: Competence in passing judgment requires knowledge.
Symbolized: Competence --> Knowledge
EDIT: What he said... ^_^
