Which symbol is representative of industrial society?

The gear symbol is representative of an industrial society because it signifies machinery, manufacturing, and the mechanization that are integral to industrialization. In industrial societies, production methods shifted from agrarian and handcraft to machine-based processes that allowed for mass production. The gear embodies the idea of mechanics and technology at the heart of industrial operations, illustrating the movement and workings of machines that drive the economy and productivity in such societies.

The other symbols do not capture the essence of industrialization as effectively. The globe might represent globalization but does not specifically indicate industrial processes. The eagle is often associated with freedom and national identity, while the tree symbolizes nature and the environment, neither of which directly relate to the mechanical and industrial themes represented by a gear.
