What is the idea behind the seismic recordings? It is to avoid the “hard rock” on the earth crust while drilling for oil reserves, right? Or they want the location of “hard rocks” and drill on that part of the rock?
If its to avoid the “hard rocks”, then in Q19, option C, the similarities of the rock characteristics means that the Rock is not hard on the other side and the seismic wave wouldn’t record anything, doesn’t this in favor for this procedure?
