Which of the following is an example of a shortage? having a sale on soda because there are too many cases on the shelf the price of grain going down when supplies are scarce the price of oil going up because more people are driving cars not having enough of one brand of soda in the store because of a sale

not having enough of one brand of soda in the store because of a sale

Explanation:

Shortage means something is not enough to satisfy the available need at that particular period.

When the brand of soda is not enough because most people have bought it that means there will now be a shortage to give those other customers who will still want to buy the same soda brand.

In this case it was inevitable since when there is a sale people buy more than they usually buy in order to store it back in their houses and this lead to shortage.
