The question asks why the bear demanded the underground produce the second time. From the textbook context, we can see the sequence: First time, the bear claimed above-ground produce. The farmer planted potatoes. The bear got only leaves and was annoyed. So the second time, the bear changed his demand to underground produce hoping to get a better share. However, the farmer then planted wheat, and the bear again got only roots while the farmer got the grain. This shows the farmer's cleverness in outsmarting the bear each time.
