Which major military technologies did the Song produce or adopt?

• A. Longbows and armor
• B. Gunpowder weapons, rockets, flamethrowers, and improved fortifications.
• C. Nuclear weapons
• D. Naval rams

Answer: (B)

The key idea is that the Song dynasty pushed warfare into the gunpowder era and strengthened defensive works, changing both offense and defense on a large scale. They actively produced and adopted gunpowder-based weapons, turning powder into practical battlefield arms such as explosive and incendiary devices. Along with this, they developed rocket-propelled weapons that could reach enemy troops and fortifications from a distance, and they employed flamethrower-like incendiaries to project fire in battles and sieges. At the same time, Song engineers and planners focused on fortifications—improved city walls, towers, moats, and other defensive works that made invasions harder and protected strategic centers. Taken together, these technologies show a clear move toward gunpowder warfare and fortified defense, which is why this option best captures what the Song produced or adopted.
