we can determine whether or not a decision / input pair is context-sensitive.
If LL gives a different result than SLL's predicted alternative, we have a
context sensitivity for sure. The converse is not necessarily true, however.
It's possible that after conflict resolution chooses minimum alternatives,
SLL could get the same answer as LL. Regardless of whether or not the result indicates
an ambiguity, it is not treated as a context sensitivity because LL prediction
was not required in order to produce a correct prediction for this decision and input sequence.
It may in fact still be a context sensitivity but we don't know by looking at the
minimum alternatives for the current input.
