01 What technical need was met by using drills of different thicknesses?
Answer and explanation
Correct answer: C. Making suitable holes in beads of different sizes
Explanation: The governing concept is the relationship between tool design and craft function. Beads varied in size and thickness, so drills with different diameters were needed to create suitable holes without breaking the stone. Those holes allowed the beads to be strung and used as ornaments. Option C is correct. Weighing stones required balances and weights, while weaving threads and colouring seals require different tools; none of those activities explains varied drill thicknesses.
