Answer:
OB. The new smelting processes made them stronger.
Step-by-step explanation:
During the Bronze Age, people learned to extract metals from their ores through a process called smelting. This process involved heating the ore to high temperatures in a furnace with a fuel source, which caused the metal to separate from the rock. The resulting metal was then melted down and cast into shapes using molds.
This new smelting process allowed for the creation of stronger metals, such as bronze, which is a mixture of copper and tin. The bronze alloy was much stronger than the pure copper that had been used in earlier times, and it could be cast into a wider variety of shapes. This gave Bronze Age societies a significant advantage in tools, weapons, and other forms of technology. Therefore, option B is the correct answer.
