Question restatement: Which of the following is true?

Option 1: 'The practice of plowing brought more rain to the Great Plains.' This statement mixes agricultural activity with meteorological outcomes in a way that isn’t supported as a primary cause of rainfall changes; plowing did not reliably bring more rain to the Great Plains, so this is not considered a true historical or climatic claim.

Option 2: 'Global temperature averages during the Dust Bowl were significantly hotter than global temperature averages in the past five years.' While the 1930s Dust Bowl era featured extreme heat in parts of the United States, claiming that global averages for that entire period were significantly hotter than the global averages of the most recent five years would require global-scale temperature data analysis. This statement oversimplifies and misrepresents global temperature comparisons, making it unreliable as a true generalization.

Option 3: 'Hundreds of thousands of migrants left the Plains states to escape Dust Bowl conditions.' This reflects well-documented historical reality: the Dust Bowl of the early 1930s caused severe agricultural disaster and drove large numbers of people to migrate away from affected areas in search of new opportunities, often termed the Okies phenomenon. The scale and direction of migration are supported by historical records, making this a true statement.

Option 4: 'The fact that many U.S. states and cities had their single hottest temperature on record during the 1930s is evidence that human-caused climate change is a hoax.' This presents a distorted interpretation. Extreme heat records in the 1930s reflect regional weather events and historical climate variability, but using that to declare a global hoax about human-caused climate change ignores long-term, multi-decade trends, broader data sets, and the difference between weather and climate. It is not a scientifically supported conclusion and thus not a true statement.

In summary, the only option that aligns with well-supported historical evidence about the Dust Bowl era is the one noting mass migration away from the Plains due to environmental disaster. The other options rely on oversimplifications, misinterpretations of data, or unfounded causal claims about climate history.
