Reason (R): The Delhi Ridge contains exposed quartzite, which provided suitable raw material for manufacturing stone tools.
Explanation
The Delhi Ridge forms the northern extension of the Aravallis and contains exposed quartzite, a hard and durable stone suitable for prehistoric tool manufacture. The availability of this raw material helps explain the concentration of Lower Palaeolithic sites in the Ridge and adjoining Aravalli landscape.
2. Assertion (A): Anangpur is significant for understanding Lower Palaeolithic tool manufacture in the Delhi–Haryana region.
Reason (R): The large quantity of manufacturing debris at Anangpur indicates that stone tools were manufactured at the site itself.
Reason (R): The large quantity of manufacturing debris at Anangpur indicates that stone tools were manufactured at the site itself.
Explanation
Anangpur is an important Lower Palaeolithic locality because it preserves a substantial Acheulian stone-tool assemblage. The presence of abundant manufacturing debris, flakes and cores indicates that tools were produced at the site rather than merely being brought there after manufacture. Therefore, the Reason directly explains the Assertion.
