Microbiologist, Dr. Hiroshi Nakamura and his team conducted an extensive study on the impact of industrial contamination on the surrounding microbial environment. By analyzing the soil and water samples in regions where contamination was prevalent, they discovered that areas closer to the contamination sites had a higher concentration of antibiotics, leading to microbial imbalance. However, these regions showed an unexpected increase in certain bacterial strains that are known to be antibiotic-resistant. Dr. Nakamura hypothesized that the contamination activities, despite causing microbial imbalance, were indirectly promoting microbial diversity by favoring these specific antibiotic-resistant strains.

Which observation, if true, would most directly challenge Dr. Nakamura's hypothesis?
