Which says a lot more about our zombie-like ways of measuring "performance" in human beings (and in high school students especially), than whether AI is actually catching up on us in any meaningful sense. (If a high school student bombed that one multiple-choice example, most likely it's because they were fatigued at the testing process itself -- it's hard to imagine them making any of the wrong choices given in an actual, real-life setting).
Contrary to my assumption that this is about people in the USA, the title mentions "Average High School Senior" but means Japanese High School student that is applying to the "Japan’s standardized college entrance test".
