 It seems clear that the truth of this sentence does not require every person with a credit card to pay his bill with each credit card he has, but merely with some credit card he has. Our comments to this point have suggested that the debate with respect to (26)/(54) and weak vs. strong readings is over which one of the two sets of truth conditions (26)/(54) have. Each of the theories discussed in this entry only assign one of the existential or universal truth conditions to relative clause donkey sentences (though this may be more of an artifact of the specific implementations of the theories than the theories themselves).
