Final answer:
The popularity of cranberry drinks (A) would not affect the position of the supply curve for cranberries. Factors related to production costs and technology in agriculture, such as land price, cost of fertilizers, and pest control development, would shift the supply curve.
Step-by-step explanation:
The factor that would not affect the position of the supply curve for cranberries is the popularity of cranberry drinks (A). Changes such as the price of agricultural land (B), the cost of fertilizers for cranberry production (C), and the development of a new pest control (D) relate directly to the production costs or technology in the agriculture sector. These aspects can cause shifts in the supply curve, as they influence the amount suppliers are willing to produce at any given price.
For example, changes in weather and climate like a drought can decrease the supply of agricultural products, leading to a leftward shift of the supply curve. On the other hand, good weather conditions would shift the curve to the right. Similarly, advances in organic farming can shift the supply curve to the right, but only when the increase in supply surpasses the increase in demand can we expect a potential drop in prices due to an excess supply.
