Answer: The agricultural act, established the first major government program to help farmers maintain crop prices with a federally sponsored Farm Board that would make loans to national marking cooperatives or set up corporations to buy surpluses and raise prices. This act failed to help American farmers. In the U.S., the first step for agricultural marketing was initiated by the Agricultural Marketing Act of 1929. The Act was introduced as a measure to stop the downward twisting of crop prices. The Act sought to help farmers in buying, selling, and storing agricultural surpluses.
Scarcity is what forces you to make trade-offs. Suppose you have an economy that produces and consumes 2 products, A and B. In a world without scarcity, you have enough resources (land, machinery, raw materials, manpower) to produce as many of each product as you need/want. However, in a world with scarcity, you have a limited amount of production resources. You can produce, let's say, 10 A products or 10 B products, or a combination of both products with less than 10 products each. For every additional A product you produce (up to the max of 10), you have to produce less B products. This is a trade-off.
