 What is the most likely cause of the accident that displaced Marjorie and Donald from their home?
Marjorie put back her head and laughed, and I was forced to join her, for we both recognize that my understanding and "feel" for commercial matters—if I may use that expression—is almost nonexistent. Back in the old Ridgeville, fifty-odd miles to the south, we had our home almost paid for, when the accident occurred. Four of them were at the barn when I arrived next morning; or rather on the rise of ground just beyond it, and the kite hung motionless and almost out of sight in the pale sky. As we trailed back to the barn I asked Doris, "How did you know that flattening the lower edge of the hole would create instability?"
