The celebs in the test. I'm not sure I could say anything meaningful about Bieber other than he's a pop star from Canada. Similar for Kardashian - Instagram influencer with lots of cosmetic surgery and makeup. Is the test expecting me to know other details beyond the completely inane and superficial?
It would be even worse if they tested on athletes. I haven't watched any of the big US sports in decades. NFL, NBA, MLB - no clue. I guess I could answer a few questions about World Tour cyclists, but that's not likely to be on a test outside of Belgium or Italy.
