This is a question of an official test, but how can you get it right when you can't understand The digitized image? Can a man of common sense easily understand that digitized (0 or 1) information can produce a rough but not detailed shapes? It's hard to understand, so only 30% of the testees got it right. I'd like to know if an average native speaker can understand this question.
ex)If you connect a primitive digital camera to your PC and aim it at a happy face, your computer might perceive the image as it appears on the right-hand side of the given drawing. The digitized image of the face is rough because the computer thinks in terms of ones and zeros and makes all-or-nothing approximations. This will, in some cases, lower subtle information about light versus dark differences, hence the lack of detail in the eyes and mouth, and in other cases exaggerate such differences, as shown in the edges of what should be a smooth, gradually curving face.
