The pestle is an ancient tool primarily used for grinding or crushing various substances, often associated with food preparation such as grinding grains or spices. Its presence suggests a society that had developed basic agricultural practices, particularly in relation to farming, where the processing of crops was essential. The use of a pestle indicates the community was not only engaged in agriculture but also had the means to process their food, which is a characteristic of societies with established farming practices.

This choice aligns well with the level of technology typically seen in societies that rely on agriculture, where such tools are essential for preparing food from harvested crops. While advanced irrigation systems, metalworking tools, and woodworking skills may reflect more specialized or advanced technology, they don't directly relate to the basic agricultural practices implied by the use of a pestle. This makes the choice of farming implements the most appropriate answer regarding the level of technology indicated by the pestle.
