Answer:
- One from natural encounters
Step-by-step explanation:
The kind of construction project displayed here would be from 'natural encounters' as it involves a structure similar to the natural establishment. This is clearly revealed through the descriptions like 'Dimtri's crawl over the area consisting of large blocks with a structure of three-sided compounds along with boards in place of the proper roof and it seeming like he was returning yo his den' Thus, it shows that the area is designed by keeping the ancient cave-like structure in mind.
