 What is the most likely cause of the accident that displaced Marjorie and Donald from their home?
SCHOENHERR "What would you think," I asked Marjorie over supper, "if I should undertake to lead a junior achievement group this summer?" "Why, Donald," she said, "it could be quite interesting, if I understand what a junior achievement group is. Some groups have built up tidy little bank accounts which are available for later educational expenses." 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. When Ridgeville moved to its present site, so, of course, did we, which meant starting mortgage payments all over again. This was to be our headquarters and factory for the summer—a roomy unused barn belonging to the parents of one of the group members, Tommy Miller. Mary McCready was a big husky redhead of twelve, with a face full of freckles and an infectious laugh, and Tommy Miller, a few months younger, was just an average, extroverted, well adjusted youngster, noisy and restless, tee-shirted and butch-barbered. "The Miller boy and Mary McCready," he had said, "have exceptionally high IQ's—around one forty or one fifty. "You should be able to make ball bearings by molding, then densify them by electroplating."
