Madden: Industrialists address problems by simplifying them, but in farming that strategy usually leads to oversimplification. For example, industrialists see water retention and drainage as different and opposite functions -- that good topsoil both drains and retains water is a fact alien to industrial logic. To facilitate water retention, they use a terrace or a dam; to facilitate drainage, they use drain tile, a ditch, or a subsoiler. More farming problems are created than solved when agriculture is the domain of the industrialist, not of the farmer. The situation as Madden describes it best illustrates which one of the following propositions?
A: The handling of water drainage and retention is the most important part of good farming.
B: Industrial solutions for problems in farming should never be sought.
C: Farmers are better than anyone else at solving farming problems.
D: The problems of farming should be viewed in all their complexity.
