Utterance: 1. i had the privilege of teaching 2. religion 3. colloquial Annotation provided in the Guideline: 1. rejectuninterpretable -- i had the privilege of teaching 2. generic:na:body -- [religion]<body> 3. generic:na -- [colloquial]<searchphrase> Question: We got very confused given these examples in the Guideline. For No.1, it seems 'i had the privilege of teaching' can also be a body of a message. And for No. 2&3, we had no idea why these two are treated differently. Frankly, the boudary description of generic and reject_uninterpretable on P345 is very helpful, but we would be appreciate if you could tell us the boundary between generic:na and generic:na:body when it comes to fragmented utterance.
