A level of organization of inferences in which competing plausible alternatives can be compared, and all but one actively rejected, is a very important aspect of any comprehension model. Multiple choice inference structures help the model stay tuned to the comprehension context, and help establish a framework in which inference producers are less likely to outstrip inference consumers, a common problem of inference systems. I look at four different modelling areas in which the same issues dominate, and suggest that the structure of knowledge is greatly influenced if one adopts the point of view which places emphasis on multiple choice.
