| 1) exact: normalized ArithMark context found inside an OpenThink question or trace | |
| 2) n-gram: shared word 13/10/8-grams between ArithMark (context + gold ending) and OpenThink (question + trace) | |
| 3) numeric signature: an OpenThink question containing every number of an ArithMark item AND giving its gold answer | |
