For the first question regarding the bowl of strawberries and white flower, the principle that is NOT represented is pattern. The arrangement of strawberries and the flower does not suggest a repetitive or regular arrangement that characterizes pattern.
For the second question about "Green Wheat Fields, Auvers" by Vincent van Gogh, the principle of design that is most evident through the artist’s use of cool colors is harmony. The cool colors work together cohesively to create a calming and unified effect throughout the artwork.
