Q. In stone age, the composite tools started appearing in which of the following ages?
Answer: Mesolithic
Notes: One of the key aspects of the Mesolithic Age was the reduction in size of well-established tool types. The characteristic tools of this age were microliths (miniature stone tools usually made of crypto-crystalline silica, chalcedony, or chert, both of geometrical and non-geometrical shapes). They were not only used as tools in themselves but also to make composite tools, spearheads, arrowheads, and sickles after hafting them on wooden or bone handles.
