My reasoning for the plain question was: as people start to replace search engines by AI chat, I thought that asking "plain" questions to see how trustworthy the answers might be, would be a good test. Because plain folks will ask plain questions and won't think about the subtle details. They would not expect a "precise number" either, i.e. not 23:06 PDT, but would like to know if this weekend would be fine for a trip or the previous or next weekend would be better to book a "dark sky" tour.

And, BTW, I thought that LLMs are computers too ;-0
