Question

contribute
inform
-ing
transform
-ed
contribute
-tion

Explanation:

We need an adjective to describe Jordan's approach to making costumes, formed by combining a root word and a suffix. "Inform" + "-ed" creates "informed", which means having knowledge, matching Jordan's actions of learning via videos, books, and talking to a teacher. Other options don't fit: "contribute" + any suffix doesn't make sense here, "transform" doesn't relate to gaining knowledge, and "-ing" or "-tion" with the wrong root can't form the needed adjective.

Answer:

A. inform, B. -ed
(Combined to make "informed" for the blank)
