In a research project examining the influence of various soil types on root development in plants, two scientists, Dr. Adams and Dr. Baker, proposed different hypotheses.

Dr. Adams argued that soil with high organic matter content would significantly enhance root growth due to improved nutrient availability.

Dr. Baker posited that sandy soil would promote better root development because of its excellent drainage properties, preventing root rot and allowing for greater access to oxygen.

Based on this information, which hypothesis presents a more robust argument regarding root development?
