Answer:
7. B
8. The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics, and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.
9. Herbert Hoover was under the impression that the stock market crash of 1929 was a simple market correction, that it would go away if everybody just acted like everything was normal, and that markets simply do these things from time to time. Billboards circa 1930 with the blurb "Wasn't the depression terrible?" kind of summed up his tone-deaf approach to massive unemployment and runs on banks. He honestly believed that government intervention was not the answer. By the time Roosevelt took office in 1933, he understood that no quick solutions were to be had. He did start a lot of public works projects, like the Works Projects Administration, and the Tennessee Valley Authority. He also instituted several "bank holidays" to discourage panic-driven depositors from taking all their money out of their banks. Austerity became the new normal in America and stayed that way until the US entered World War II.

It depends on which tribe it was, some were friendly, some were not
It is sometimes a minor pest of cotton, feeding mostly on young shoots, piercing the stems and sucking the sugar-rich juices intended for shoot growth. It has been known to cause the introduction of a fungus, which rots the cotton boll. Nymphs feed on seeds in very small bolls or in opening bolls.
The boll weevil (Anthonomus grandis) is a beetle which feeds on cotton buds and flowers. Thought to be native to Central Mexico,[1] it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South. During the late 20th century, it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the U.S. allowed full-scale cultivation to resume in many regions.
Adult weevils overwinter in well-drained areas in or near cotton fields,and farms after diapause. They emerge and enter cotton fields from early spring through midsummer, with peak emergence in late spring, and feed on immature cotton bolls.
The boll weevil lays its eggs inside buds and ripening bolls (fruits) of the cotton plants. The female can lay up to 200 eggs over a 10- to 12-day period. The oviposition leaves wounds on the exterior of the flower bud. The eggs hatch in 3 to 5 days within the cotton squares (larger buds before flowering), feed for 8 to 10 days, and finally pupate. The pupal stage lasts another 5 to 7 days. The lifecycle from egg to adult spans about three weeks during the summer. Under optimal conditions, 8 to 10 generations per season may occur.
