 (30) can mean either that Sam loves Jess more than he loves Jason or that Sam loves Jess more than Jason loves Jess. This ambiguity arises from phrasal and clausal comparatives: the phrasal comparative of ‘more than’ takes a noun phrase and relates Jess and Jason (effectively saying that the degree to which Sam loves Jess exceeds the degree to which he loves Jason). On the other hand, one can read (30) as involving ellipsis in which ‘loves Jess’ is stripped from the complement of Jason and left sotto voce.
