| 金声玉亮2.0 | D. Lower factor prices in major industries. Explanation: An expansionary supply shock occurs when there is an increase in the supply of goods and services, often due to a decrease in production costs or an improvement in productivity. Lower factor prices in major industries would lead to a decrease in production costs, making it cheaper for firms to produce goods and services, and thus increasing the supply of those goods and services. This is an example of an expansionary supply shock. The other options are not correct because: A. Rapidly increasing wages would actually be a contractionary supply shock, as higher wages would increase production costs and reduce the supply of goods and services. B. A greatly depreciated currency would be a demand shock, not a supply shock, as it would affect the price of imports and exports. C. Declining labor productivity would also be a contractionary supply shock, as it would reduce the efficiency of production and increase costs. |

| deepseekr1 | D. Lower factor prices in major industries reduce production costs, enabling firms to increase aggregate supply. This aligns with an expansionary supply shock, which boosts output while potentially lowering prices. Other options (A, B, C) describe scenarios that raise costs or reduce productivity, leading to contractionary effects. Answer: D |

| doubao | D Expansionary supply shocks increase the economy's productive capacity and shift the aggregate supply curve to the right. Lower factor prices in major industries can lead to lower production costs and an increase in supply, which is an example of an expansionary supply shock. Rapidly increasing wages and declining labor productivity would likely have the opposite effect. A greatly depreciated currency can have various impacts but is not typically considered a direct expansionary supply shock. |

| kimi | D. Lower factor prices in major industries An expansionary supply shock is an event that increases the productive capacity of an economy, leading to an increase in supply without a corresponding increase in demand. Lower factor prices in major industries can lead to lower costs of production, which can increase the supply of goods and services in the economy. This is because businesses can produce more at the same cost, or they can produce the same amount at a lower cost, which can lead to an increase in supply. |

| wenxinyiyan | D Explanation: An expansionary supply shock refers to a sudden increase in aggregate supply, often due to technological improvements, lower production costs, or other factors that increase productivity. A. Rapid increasing wages would increase production costs, thus reducing aggregate supply. This is not an expansionary supply shock. B. A greatly depreciated currency might initially boost exports, but it does not directly affect the aggregate supply in a way that would constitute an expansionary supply shock. Currency depreciation mainly affects demand, not supply. C. Declining labor productivity would reduce output per worker, thus reducing aggregate supply. This is not an expansionary supply shock. D. Lower factor prices in major industries would reduce production costs, allowing for greater output at lower prices. This is an example of an expansionary supply shock because it increases the aggregate supply of goods and services. |

| zhipu | D. Lower factor prices in major industries An expansionary supply shock is an event that increases the total supply of goods and services in an economy, leading to lower prices and higher output. Lower factor prices in major industries (such as reductions in the cost of raw materials or energy) can significantly reduce production costs, thereby increasing supply. The other options (A, B, and C) would typically lead to higher production costs or reduced supply, making them examples of contractionary supply shocks. |
