Verified step by step guidance

1. Understand that a supply curve shows the relationship between the price of a good and the quantity supplied, holding other factors constant.
2. Recall that a shift in the supply curve means the entire curve moves either left or right, indicating a change in supply at every price.
3. Identify factors that cause shifts in supply: changes in input prices, number of sellers, and technology are all external to the good's own price and affect supply directly.
4. Recognize that a change in the price of the good itself does not shift the supply curve but causes a movement along the supply curve (change in quantity supplied).
5. Conclude that the factor which does NOT cause a shift in the supply curve is a change in the price of the good itself.
