Final answer:
An improvement in production technology leads to a reduction in production costs, which, in turn, causes the supply curve to shift to the right, indicating an increase in supply at any given price. Option a. supply curve to the right is the correct answer.
Step-by-step explanation:
The question is addressing a fundamental economic principle related to how improvements in production technology affect market conditions, specifically the supply curve. When there is an improvement in production technology that reduces the cost of producing goods, firms are able to produce more quantity at each price level, leading to a shift of the supply curve to the right.
This rightward shift signifies an increase in supply. These improvements can manifest in various ways, such as through the Green Revolution, which significantly increased the harvest per acre of crops like wheat and rice due to the use of improved seeds. On the other hand, factors such as improvement in product quality and increase in need will generally cause the demand curve to shift to the right, not the supply curve. Such shifts represent an increase in consumer demand for goods at given price levels.
