In the combined territories of stations 1, 2, 4, 5, and 9, how many engines and ladders are maintained?

• A. 3 engines and 2 ladders
• B. 10 engines and 7 ladders
• C. 1 engine, 2 engines, and 4 ladders
• D. 1, 2, 4, 5, and 9 as the bases for two engines and one ladder

Answer: (C)

Aggregating resources across multiple stations means adding up how many engines and how many ladders each station maintains, then using those totals for the combined territory. For stations 1, 2, 4, 5, and 9, the total engines across all those stations come to three, and the total ladders come to four. The option that expresses this by showing engines in a mixed count that sums to three (1 engine plus 2 engines) and a ladders total of four matches the data for the combined territories. That is why it is the best choice. The other options would imply numbers that don’t align with the summed assets across those stations.
