Looks up a sentence label from the model. Small models often wrap the label in extra
text ("Passage 2: [S6] Most of…", " s3 "), so the first S-number found is used. Some
write the sentence out instead of its label: that is accepted only when it appears word
for word in exactly one sentence of the material (at least MIN_WRITTEN_WORDS
words), and the whole real sentence is returned.
