I need to answer the question, so could you give me an example of the question's answer?

What is an example of (just) one thing that could happen today in the United States, which would result in a decrease in the Supply (Curve) of a product that you are familiar with?

Your posting should be at least two paragraphs long, and reference (just) one of the typical factors of supply highlighted within Chapter Three. You should also specify a particular business firm (by name) that is a supplier in the Product Market, and identify (just) one specific good or service that they sell.

(Please note that the one thing that cannot cause the Supply for a product to change would be for the price of the product itself to change - this only changes the quantity supplied by business firms).
