$(1)$ Plaster of Paris is used to join fractured bones and keep them immobilized.
$(2)$ Calcium carbonate and soil are the raw materials for cement production.
(A) $(1)$ True: Plaster of Paris $(CaSO_4 \cdot \frac{1}{2}H_2O)$ sets into a hard mass when mixed with water,making it useful for orthopedic casts.
$(2)$ True: Cement is manufactured by heating a mixture of limestone $(CaCO_3)$ and clay (which provides soil components like silica,alumina,and iron oxide) in a rotary kiln.
