Answer: High price of potatoes.
Step-by-step explanation:
Potato crops in Idaho have been damaged by plant disease. If the diseased crops will die then there will be a massive shortage of potatoes in the market.
This will increase the demand of potatoes in the market and the supply will decrease with an increase in the price of the potatoes.
So, there will be a scarcity of potatoes in the market with increased price of the left over potatoes.
