@dalias @PhoenixSerenity @giflian That has always bothered me, too. There are infinite possible well-behaved, rule-based sequences that start with any given prefix. And asking the test taker to use simplicity as a guide overlooks that there are different "alphabets" of basic operations that can be used to express them, so even that is contextual.
It always stuck out more for the verbal questions for me, though. Those were the ones where I was likely to not only get the question wrong, but be so irritated and frustrated with the ill-defined nature of the question that I ended up leaving a note in the margins criticizing the test's quality. There's a reason autistic people are better at puns. We see way more possibilities, and make way fewer assumptions about what's the "correct" way to interpret something.
