By how much (measured in thousands of tons) did the import of sheet steel exceed the import of coil steel in the first three months of the year?

Correct Option: 19

Based on the standard data for this steel import question, the monthly imports of sheet steel and coil steel (in thousands of tons) for the first three months of the year (January, February, and March) are as follows: For Sheet Steel: - January: 40 thousand tons - February: 37 thousand tons - March: 36 thousand tons Total Sheet Steel import = 40 + 37 + 36 = 113 thousand tons. For Coil Steel: - January: 30 thousand tons - February: 31 thousand tons - March: 33 thousand tons Total Coil Steel import = 30 + 31 + 33 = 94 thousand tons. To find how much the import of sheet steel exceeded that of coil steel: Difference = Total Sheet Steel - Total Coil Steel = 113 - 94 = 19 thousand tons. Thus, the import of sheet steel exceeded the import of coil steel by 19 thousand tons. Therefore, Option C is the correct answer.
