Answer:
an increase in the price of both
Step-by-step explanation:
A decrease in the supply of paprika would cause an increase in the price of both substitute goods. When the supply of paprika falls, the demand will be greater than what is available for sale and this would cause the sellers to raise it's price afterall it is now scarce.
Also as a substitute good, more people would begin to switch to buying cummin which would raise the demand for cummin. This increase in demand for cummin would then cause the price of cummin to go up.
