A narrow bag key

A fictional first collection names a bag drawing CARRY and a basket drawing also CARRY. CARRY returns both. CUP returns nothing because CUP is not an entry. In a second collection only the bag key changes from CARRY to BAG; the basket remains CARRY. CARRY in the second returns only basket. Both complete collections are kept separately. No shopping or carrying has occurred.

Use after this target and an accessible response route have actually been offered. Confirm this whole source and staff responses have not been seen; otherwise label practice. A later offer requires a fresh whole source and an intervening teaching opportunity. Without prior evidence call it current first evidence, not progress.

Read the exact source neutrally, reread, use broad pointing/card movement/usual communication or scribe exactly as directed. Record actual help and prompts. Do not supply a model, explain an answer or fill the four own spaces before an attempt. Pass, private response, pause or a smaller later offer remain valid.

These source responses do not alone prove actual device familiarity/use, an actual learner-owned contribution, calibrated QCAA bands or causal gains. Those are separately observed evidence.

One selected prompt may be enough. Leave all unused places empty.
