Answer: (paragraph 6)
Step-by-step explanation:
The sentence that best supports the inference that there is a relationship between the historical creation of charcoal and deforestation is: "If a worker used one hundred pounds of wood, he or she would most likely only produce about twenty pounds of charcoal. People had to cut down many trees to feed these wasteful fires." (paragraph 6). This sentence suggests that the process of creating charcoal in the past was not efficient and required a lot of wood, which could lead to deforestation.
