Assertion (A): Incoming clay is tested for moisture on every delivery.
Reason (R): The recipe is weighed on a dry basis, so the mass to be weighed out depends on the water the clay is carrying.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the necessity: two loads of the same clay at eight and fourteen per cent moisture need different weighed masses to deliver the same dry solids, and nothing else in the batch reveals the difference.
