Could you accept that these assumption are frequently made incorrectly? Let us say I went shopping, and I know that I purchased eight jars of sandwich spread. I know that six of the jars had a mixed peanut butter/jelly stuff that you can squeeze out, and I remember the other two had peanut butter in a glass jar, but I can't remember if they were mixed or not, and I say, of those eight jars, "Six of the jars had jelly, the rest had peanut butter" - because that's all I was certain of - that somebody then inferring that the six jars did NOT have peanut butter, and that the other two jars did NOT have jelly -would be wrong in doing so? It's entirely possible that the question was poorly put together, and the answers provided were not sufficient to correctly answer the question. Test makers aren't all perfect beings - as clearly demonstrated by this test.
