A low bar should still be helpful, but this is more of a google search than a rationality check. They could have at least changed the numbers slightly or the nouns by a bit. If it were to check if you were a computer, it wouldn't work at all because the answers are the same each time.

Of course, answering them incorrectly is still a bad sign. I just imagine that with a 3 minutes of more effort (especially compared with the multi-year long complex web application) they could have had something substantially more useful and interesting.
