I had asked the machine about the spraying of the sky, which has exploded this year where I live.* I got totally unsatisfactory answers, full of deflections, so to test its answering capability I tried a query I "knew" the answer to (ie "knew" to the extent that it wouldn't be able to bullshit me).

* In fact, just the other day here at the FIFO concrete plant, the sky was more full of trails than I have ever seen anywhere. It was so bloody obvious even a couple of the other drivers woke up to it. One even asked me questions later in the mess hall.
