I had to get past a captcha for automation and the solution I came up with was to always choose 2. If it was incorrect, just request a new captcha until it passed. For some reason, 2 was the answer most of the time so it actually rarely had to retry anyways
I’m getting flashbacks to LensLok™; the two-letter codes were often very hard to read though the plastic lens, and when you’d get the code wrong enough times, you’d have to load in the entire program again (from tape!), which took ages. There was also a “training” mode, of sorts, to help people familiarize themselves with reading the codes. In the training mode, the code letters were always “OK”. But here’s the kicker: For some unfathomable reason, the real code was very often (but not always) also the letters “OK”! So it was easier (at least on your eyes) to just always enter the letters “OK”, and hope it worked. What time you lost reloading for when it didn’t work you’d save by not having to adjust the scale to the size of your TV every single time.
I found one video demonstration: https://youtu.be/Wpn9sLNg-6k?t=310
