B) motion parallax
C) texture gradient
D) linear perspective

Motion parallax is the cue that allows Andre to perceive the closer buildings as moving faster than the distant buildings as they pass by his view from the window of the moving train. This is because closer objects move across the visual field faster than do more distant objects when the observer is in motion. Aerial perspective works by creating a bluish haze as objects recede into the distance, while linear perspective uses converging lines to give the impression of depth. Texture gradient works by showing a change in the detail in objects as they move into the distance.
