A pair of possible descriptions for simultaneous transfers of the demand for clothing from D0 to D1 while the supply of clothing transferred from S0 to S1 could be which: (1) unexpectedly cold and frequent blizzards caused Minnesotans to buy more woolens, when an epidemic which made sheep go bald drove down the price of wool. (2) global warming caused the silkworm population to explode and mature exceptionally quickly, and fashionistas persuaded lounge lizards to wear only last-year's vintage denim. (3) college fraternities needed their pledges to wear three-piece suits 8 hrs daily and to donate all T-shirts to the Salvation Army. (4) deforestation decimated the population of wild acrylics within a single season when surfers began wearing head-to-toe scuba suits while cancer via sun damage became rampant. (5) textile employees responded to stiff tariffs on imported apparel along with a nationwide strike.
