The correct answer is "repairing a cracked sidewalk". Repairing a cracked sidewalk is a process that should be done following by placing details in order of importance, since if the solution is not ordered, the sidewalk could not be properly repaired. For instance, if the sidewalk is not cleaned before the cracks are filled with premixed concrete filler, the repaired sidewalk could be weak as it would have dirt in the new concrete.
