It is not equivalent to either, though I claim that the first and third
have identical truth functions (which doesn't seem to be quite what you
mean by "truth-functionally equivalent".) It is certainly not
truth-functionally equivalent to the "ma jei broda", because 1) the
answer to the two questions differs and 2) the correct filling in of the
"ma" with "la fals" is a true statement. So by my above statement "xu
broda" is false, whereas the jei statement is true when filled in with a
correct value for ma (and the existence of a value that makes it true,
makes the bridi with ma "true").
