Coordination under Right Node Raising

The sentence in (1) has a collective reading, under which Mary and Susan is interpreted as being a conjoined object for both verbs (i.e., John loves both Susan and Mary, and Peter hates them). We will not deal with this reading here. The reading we are interested in is the distributive one, in which Mary is interpreted as the exclusive object of love, and Susan as the exclusive object of hate. Note that under the distributive reading of (1), only crossing dependencies are allowed between the verbs and the objects. Nesting dependencies are ungrammatical. That is, (1) can only have the meaning in (2a)
