Final answer:
An invention of a new and more powerful computer chip by Intel would increase the long-run aggregate supply as it represents a technological advancement that boosts productivity and economic growth. option a.
Step-by-step explanation:
When Intel invents a new and more powerful computer chip, this would likely increase long-run aggregate supply (LRAS). An improvement in technology, such as a more efficient computer chip, enhances productivity. This kind of technological innovation allows firms to produce more goods at every price level, leading to a rightward shift in the LRAS curve, signaling economic growth. It demonstrates how advancements in technology are a pivotal determinant of aggregate supply, particularly in the long run where the economy's productive capabilities are concerned.
