The primary purpose of the Rule of V's in geological interpretation is to interpret bed dips and trends. This rule states that when looking at a valley or stream, the "V" shape formed by the stream or valley will point upstream toward the higher ground and the direction of dip of the sedimentary layers will be indicated by the orientation of these V’s. In practical terms, if one observes the V's pointing into a hillside or mountain, it suggests that the rocks are dipping away from the viewer in the direction of the point of the V. This insight is essential for understanding the geological structure and the arrangement of sedimentary layers in a given area, making it a critical tool for geologists when mapping and interpreting geological formations.

Understanding the other options can provide additional clarity; determining sediment age and analyzing mineral composition, while important aspects of geology, do not directly involve the visualization method and structural orientation that the Rule of V's provides. Similarly, identifying fossil placements pertains to paleontology rather than the physical structure indicated by the Rule of V's. Thus, the focus on interpreting bed dips and trends is what makes this rule a vital component of geological analysis.
