Clearly I've eaten too many dim sum and have become a little slow.

But in what sense could a 25 response cloze passage be seen as one item of a four 
item test?

With either the PCM or the RSM the model requires ordered categories. So, surely 
with the RSM we must have the same 25 missing words in each passage and in the 
PCM...? or we are expecting local dependence due to one stem, so using the super-
item approach?

so please tell me what I've missed . . .
