which in turn reminds me of the joke about the scientist doing an experiment on spiders...a bit morbid so you spider lovers may want to stop here.
This scientist is exploring spider mobility. He takes off one leg from a spider and yells "WALK"
and the spider limps along easily
A second leg is removed and the scientist yells "WALK"
with a bit more trouble the spider is able to walk
Five more legs come off each in succession, and after each command to WALK the spider limps along more and more feebly
Finally with all his legs removed, the scientist yells WALK at the spider and the spider just sits there.
The scientist notes in his notebook "spiders with all their legs removed lose their hearing."
A post hoc ergo propter hoc fallacy joke, confusing correlation with causality.
Its late...

The developers of PISA items try to ensure that they are not dependent upon a particular curriculum by providing sufficient context within the question to find the answer, so the answers do not depend on factual recall.
> Incidentally, the last spider I saw had three legs. It was having difficulty not walking in circles.
