question:  Why does Adam refuse to play checkers?
context: EVERYTHING IT HAD WAS IN THE GARDEN BY R. A. LAFFERTY Naturally they did not get results at once, nor did they expect to; it required a fine adjustment. But they were disappointed that they found nothing for several hours as they hovered high over the rotation. As though there were but one city, if that is its form. But this might be so varied or so unfamiliar that often both the machine and the designer of it were puzzled as to how to read the results.
