Suppose exactly three things broda. Then the right hand side
is true (some things are broda and they are all the brodas) but
is the right hand side true?

pa da broda ijo ge su'o de broda gi ro di poi broda cu du de
Exactly one thing1 is a broda iff some thing2 is a broda and
every thing3 that is a broda is that thing2.

Sorry, I was taking quantifiers as always particularizing (the normal {ro} etc, rather than the occasionally useful which goes by subpluralities. With that then, I am not sure what happens, but presumably both sides are false (since some of the subpluralities are not identical with the overall one and there are more than one plurality which brodas).
