How the answer key is structured

Each group is based on function. A stablecoin group might connect reserve, redemption, attestation, and depeg because they all describe how a token tries to keep a reference value. An AI group might connect prompt, context window, inference, and evaluation because they describe model workflow.

What to review after solving

Pick one missed group and read the definitions before moving on. The goal is not to memorize all 16 cards at once, but to notice the concept that made four terms belong together.
