Which limitation constrained use of gunpowder in Song dynasty trebuchets, making sustained bombardment difficult?

💡 Explanation

Batch variability limited sustained bombardment because gunpowder composition varied significantly, influencing explosive power and reliability; therefore explosions would likely be inconsistent, rather than the others, which influenced other parameters of the design.
