Associate
The candidate pairs items within a single set.
An associate interaction has one set of items, and the candidate pairs them with each other. Unlike a match, a pair has no direction: pairing A with B is the same as pairing B with A.

Answering
The candidate drags one item onto another, or picks one up (click it, or press Enter) and then activates a second. Each pair is listed under the items with a Remove button. An item cannot be paired with itself, and the same pair cannot be made twice. An item that has reached its match-max stays where it is and takes no more pairs.
Scoring
The response is a set of pairs, compared without regard to their order. Score it by Exact match or Mapped.
In the editor
The Insert menu does not offer it yet. Import one, or write it in the item’s source. Once in the bank it can be edited like anything else.
