Definition
Superior- If a character stands higher than another character more than 50% of the time, it is considered as superior
Higher-When one of two reference points on the characters, originally of the same height, is of a greater altitude than the other reference point

From the data collected, the monkey is above the giraffe for 1 min 16 s, which is 69.1% of the total time, 1 min 50 s. (cor. to 3 sig. fig.)
As 69.1% > 50%, therefore the monkey is more superior than the giraffe.

b) Maximum vertical distance:Scale of the image=1 unit to 0.795 cm (cor.to 3 sig. fig.)Maximum distance between two characters on the image=26.786 unitsActual distance between two characters = 26.786 X 0.795 = 21.3 cm (cor. to 3 sig. fig.)
