the wording of the question is atrocious. But if you remember
   school, questions ARE often trick questions. I remember them all
   through school. It's not impossible by accident. I've seen it in
   my nephew's 4th + 5th grade math work. [also Common Core, but
   they did this shit to me in elementary school as well: purposely
   confusing]. They're trying to force you to think outside of the
   box by making you WRONG. You're wrong here, you're wrong, there,
   you're wrong wrong wrong. Over time, you get pissed off at being
   wrong, and decide to follow the teacher's instructions no matter
   HOW confusing it is until you can duplicate what they are doing
   so that you're NOT wrong. So, they THINK they're teaching
   lateral thinking but it's not. It's "grit". They're trying to
   teach grit. That's what they call it. They've got a whole BOOK
   on grit and teaching that was very influential a few years ago,
   although aspects of it where definitely already there when I
   went to school. What pisses me off is: It teaches you to NOT
   trust the teachers. "What trick are they going to pull NOW?"
   "Where's the catch here?" Perhaps it's a good thing in the end.
   But I've seen school crack people, just like army bootcamp
   cracks some people and I don't think it's right at all. One of
   my biggest surprises in college and adult life is: Adult tests?
   They don't' trick you. THey WANT you to pass. Kid tests? They
   want you to fail. I don't think the constant oppression is
   right.
