You are still editing what appears to be a direct quote with no
indication of any alteration.  That's not honest.  If you think my words
are incorrect of misleading, here's what you should write:

None of the E(k) are empty.  My sequence used lots of empty sets.  You
tried to look clever by saying "one empty set would be sufficient" but
now you can't show that sequence.
