Your friend Casey is a Chemistry major who likes to give you a hard time for enrolling in a Psychology course. “Psychology isn’t a science,” he claims. “It’s all just common sense anyway.” Why is Casey wrong about Psychology?

In 1914, alabama produced 1.7 million bales of cotton, but three years later produced only 515,000, bales. meanwhile, in georgia, 5.2 million acres of land was dedicated for cotton production in 1914, but by 1923 there were just 2.6 million acres used for growing cotton. all of this was the result of the work of a tiny insect: the boll weevil. alabama and georgia first felt the effects of the boll weevil at different times. what would account for this difference in timing?
