The Body Farm, officially known as the Forensic Anthropology Research Facility, was established in 1980 by Dr. William M. Bass at the University of Tennessee. Its primary purpose is to study the process of decay in human remains in a controlled environment, enabling researchers to better understand forensic science and aid in criminal investigations.
Given the options you've provided, the appropriate response regarding the opening of the Body Farm would be:
1990-present
However, since the Body Farm itself was opened in 1980, it technically falls just before the "1990-present" range but after "1900-1988." If the responses pertained strictly to the opening year, "1900-1988" could also be applicable by that logic, but your specified timeframe suggests a focus on ongoing developments post-establishment.
