Restoration of a worked-out quarry commonly involves

  • A.leaving the site in exactly the state that extraction left it
  • B.removing all the remaining stone right down to ground level
  • C.replacing the stored overburden and re-establishing vegetation
  • D.filling the whole of the void back in with fresh limestone

Answer: C

The soil and subsoil stripped at the outset are kept for this purpose, which is one reason they are stored rather than discarded. Restoration is generally a condition of the planning permission rather than a voluntary act.
