Answer: raise; reduce
Step-by-step explanation:
A Supply shock is described as a situation where the supply of a good changes suddenly/ abruptly due to an unforeseen event.
Supply shocks can be positive but are usually negative so we will assume the supply shock is negative here.
If there is a negative supply shock, the amount of goods being produced will reduce abruptly which will force the supply curve to shift left.
It will then intercept the the demand curve at an equilibrium level that has a higher price and a lower quantity of output.
Think of it this way. Negative supply shock ⇒ less goods ⇒ scarcity ⇒ higher prices.
