← HistoryDuring China's Song Dynasty, which outcome increased after rapid adoption of coke-fired iron production?
A)Ballistic range of arbalests increased✓
B)Ship hull corrosion rate decreased
C)Cast iron bridge tensile strength improved
D)Blast furnace energy input declined
💡 Explanation
Increased high-carbon iron, essential for powerful arbalest firing mechanisms, enabled longer ranges because higher carbon content allowed for stronger, more resilient trigger components that could withstand greater strain, therefore ballistic range increased rather than alternatives related to corrosion, tensile strength, or energy consumption.
