you have to remember that humans usually don't so much read the directions as skim them and haphazardly extract key phrases and general hints.

also, normal rules of conversational structure make people assume that one question is an elaboration on the previous question if at all possible.

and, unfortunately, one of the easier important words to insert or drop in misreading is ‘not’.

if you want to minimize misreading, i would:

1. avoid the word ‘world’.
and
2. not put those two questions next to each other.
