On Q3, the contrapositive is throwing me (power without corruption → lift hammer → pure → worthy) because it did not say "only beings who are pure of heart can lift it". So, just because you are not pure does not mean that you can't lift the hammer. Can anyone shed some light?

I just have to say that I am feeling a bit discouraged at this point. Maybe I am studying too late in the evening after working a full day. I just feel like I should be answering more questions correctly at this point.
