A market change and three unsupported additions

A fictional classroom exercise describes a seasonal fruit arriving at a local market in much larger quantities while the relevant demand relationship and other conditions are assumed unchanged. Students are asked to interpret the ordinary supply-and-demand model. One answer says demand vanished, another invents a government price ceiling and a third attributes the change to money issuance without any information about monetary conditions. The teacher wants a short explanation that follows the supplied mechanism rather than adding facts. This is an original teaching scenario, not an actual market report or a prediction for every crop, and no exact price or policy is supplied for students to fabricate.
