Final answer:
The Conical Tower and Circular Wall of Great Zimbabwe are made of stone, not wood. The mention of wood in the passage refers to the lightweight roofs.
Step-by-step explanation:
The statement 'The Conical Tower and Circular Wall of Great Zimbabwe are made of wood' is False. The Conical Tower and Circular Wall of Great Zimbabwe are actually made of stone. As described in the text, the Great Enclosure, which is part of the Great Zimbabwe ruins, has massive elliptical drystone walls thirty-five feet high and seventeen feet thick. The mention of wood in the passage refers to the lightweight roofs that were made from wood, rather than the entire structure being made of wood.
