Apparently government intervention is wrong, but when I put productivity, productivity was wrong too. It's only something to do with aggregate supply so consumer spending, investments, net exports, and government spending are wrong.
That leaves price, resource cost, and political or environmental phenomena.
Out of those, I'm gonna choose resource cost. Will update
Explanation:
<h2>UPDATE:</h2><h2>RESOURCE COST IS CORRECT!!!!!!!!!!!!!!!!!!!!!!!!!!!</h2>
