 These examples and others suggest that whether a given relative clause donkey sentence appears to favor the strong reading or weak reading is influenced by a variety of factors, including the monotonicity properties of the determiner on the wide scope quantifier, the lexical semantics of the predicates occurring in the sentence, and general background assumptions concerning the situations in which we are to consider the truth or falsity of the sentences. However, it is very hard to find significant generalizations regarding under what conditions a given reading is  favored.[32]  Further, it is very hard to find sentences that clearly allow both a strong and a weak reading.[33] This makes the view that the sentences actually possess both readings as a matter of their semantics at least somewhat suspect. If they really do possess both readings, why is it so hard to find sentences that clearly allow both readings? And finally, relative clause donkey sentences fronted by the determiner “some” seem always to only have the existential truth conditions:
