Question

¿quién es cadence? incluye el artículo definido.
frank mallory rocky luke cadence
cadence es h de luke.

Explanation:

To solve this, we analyze the family tree. Frank and Mallory are a couple (indicated by the ring), and they have Luke and Cadence as children. In Spanish, for a female sibling, the relationship from Luke's perspective: "hermana" (sister). The definite article for "hermana" (feminine, singular) is "la". So we need to fill in "la" and "hermana".

Answer:

la; hermana
