Assertion (A): Changing the firing schedule is a poor first response to a defect that appears after firing.
Reason (R): Many defects that become visible in the kiln were created at an earlier stage.

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

Answer: B

Both are true and the reason gives the trap: the kiln reveals faults built into the green ware, so altering the schedule addresses the symptom while the real cause continues unchanged. Two changes at once also make the result impossible to read.
