premise: But between water and watt there are fifty-four main entries in Cobuild and 148 in CED . They share such entries as water biscuit and waterworks . But in addition CED alone enters water measurer ( a `bug ' ) , Watford ( a `town north of London ' ) , etc .
hypothesis: Cobuild and CED both contain water biscuit and waterworks , but only CED ahs water measurer .
