There was a rapid increase in the number of sod farms in Michigan in the years following the Korean War.

• A. Not sure
• B. False
• C. True
• D. Increased modestly

Answer: (B)

Think about what a “rapid increase” would look like in the data. If, after the Korean War, the number of sod farms in Michigan jumped sharply from one year to the next, that would support the claim. But if the records show only a steady, gradual rise over several years or only small year-to-year changes, then there isn’t a rapid surge.

In this case, the evidence typically shows growth in Michigan’s sod industry as suburban lawn demand expanded, but not as a sudden spike right after the war. Growth tended to occur gradually over time rather than as a sharp, short-lived boom. That’s why the statement isn’t supported, making the conclusion that the claim is false.
