-
C.
watershed
A watershed is a land area that channels rainfall and snowmelt into streams and rivers, ultimately draining into a common outlet such as a larger river, lake, or ocean.
-
D.
watershed divide

- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
