I want to know the answer to the following question:
What features about the ditches suggests that it was built by people under a leader's command?
All the background I'm provided with is that "These structures (and their later counterparts such as causewayed enclosures, burial mounds, and henge) required considerable time and labour to construct, which suggests that some influential individuals were able to organise and direct human labour — though non-hierarchical and voluntary work remain possibilities.". Is that enough to answer the question?
Answer: yes
