> is there a particular reason that one would assume that the first two lines are directives and the third line is what we are being asked to validate?

A much less narrow assumption is required to reach answers of "false". Think of each example as a system of simultaneous equations.

Since this test was seemingly designed relying on the idea of destructive updates, none of the given examples have satisfying assignments. But of course standout easy-pick answers of "no solution" would ruin the test. I'd really like to see a similar study of psychologies that took into account different programming bases. Perhaps such a test would even be a good way to sort students into separate intro classes that used a language suited to their preexisting mental model.
