At First I was curious why the "Not a Robot" visual quiz was not exact in it's question. For example, if the picture asked "check all the squares with the Fire Hydrant", I would check all the squares with the fire hydrant; even the ones with just a small portion of the fire hydrant. Then, I would get another "Not a Robot" quiz because obviously I failed that one.
The "Not a Robot" quiz is little by little teaching you to not be exact. The "Not a Robot" quiz is training you to not pay attention to detail. The "Not a Robot" quiz is not my favorite at this point, and I will avoid if possible all websites that use this "Quiz".
