This question examines the understanding of the important role of socialist spiritual civilization construction. The positive and negative understandings and different results of "Feng Shui Treasure Land" in the stem materials fully illustrate the important significance and great role of spiritual civilization construction, so item B should be chosen. The phenomenon reflected in the materials does not belong to religious belief, nor is it a rural land contract or agricultural investment. Therefore, reading A, B and D does not meet the meaning of the question.
