CLC Stage 31-32: What is Qui doing?

Is this QUĪ, QUAE, QUOD, relative pronoun (who/which) or something else?
1) antecedent followed by a form of QUĪ, most likely “who/which”
2) a connecting relative begins a sentence = ET + PRONOUN like hic, haec, hoc or is, ea, id (connects back to a person or thing mentioned in the previous sentence)
3) QUOD after a verb, most likely “because”; if after a noun, probably "which"
4) QUAM after a comparative, “than”
