What is the Eiffel tower made of?
C
Correct answer
Explanation
The Eiffel Tower is constructed from puddled iron, specifically a type called 'puddled iron' which was the state-of-the-art material of the 1880s. It weighs approximately 7,300 tons of iron. While steel is stronger, the tower predates widespread steel construction in France. Lead and copper were not used as primary structural materials.
