if the water rises to high it can end up damaging home, because water and leak past an old sealant, and water also rots wood, but not only will it cause damage but it could infact end up being fatal if it gets too far out of hand, a way to prevent this from being fatal is to rise water leaves with extreme caution and keep a meter my the leaves so you can tell it they get dangerously high so that way you can prevent an accident before hand. it water levels are kept well and in a good range this will prevent any injuries are fatal accidents happening as well as home being ruined. But as another precaution make sure you freshen up the sealant on your walls or wherever it may be and it your house it made from wood be sure your at a higher area of ground to the water flows away from your house
The question is asking to state the technique that allows the results of the survey to be generalized to larger population and I would say that is should be Random Sampling. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification
