Answer:
The lack of orange juice represents scarcity.
Explanation:
This is because scarcity is the lack of product, not the lack of demand. Since there is a limited supply of workers then it is less likely to be produced in large quantities, making it scarce because there is not enough of the product to meet the demand. Furthermore, the grapefruit juice cannot be considered scarce because although there is a low demand, the product's production is not threatened in any way, so there is enough of it to satisfy the demand.
