You didn't present some context on how you reached this content on the website. It looks as if it was an exercise to produce a shader detecting edges based on derivative functions or just sampling neighboring texture pixels.
The title is "Vector of Change" and the description is "Your challenge is to make something as close as the expected shader." and that's all the context you get. It doesn't seem like a very well-designed exercise.
The expected output to the quiz does not seem like something someone would intentionally choose
