Why is it important for the artist to show the highlights and shadows in this image?

A. To show the different textures present
B. To show the ridge and opposite sides of the sand dunes
C. To show the different colors present
D. To show the different lines present

B. To show the ridge and opposite sides of the sand dunes

B. To show the ridge and opposite sides of the sand dunes

The correct answer to the question is B. To show the ridge and opposite sides of the sand dunes.

When analyzing an image, it is important for the artist to show the highlights and shadows to represent the three-dimensional aspects of the subject matter. In this specific image of sand dunes, the highlights and shadows help to convey the form and shape of the dunes. By highlighting specific areas with light and shading others with darker tones, the artist is able to create a sense of depth and perspective.

Choice A, to show the different textures present, is not the main reason why highlights and shadows are important in this image. While textures can be represented by varying amounts of light and shadow, the primary focus here is to show the form and shape of the sand dunes rather than the specific textures.

Choice C, to show the different colors present, is also not the primary reason for highlighting and shading. While color can enhance the overall visual impact of an image, it is not the main purpose in this case. The primary goal is to represent the three-dimensional aspects of the sand dunes.

Choice D, to show the different lines present, does not apply to this question at all. The use of highlights and shadows does not directly relate to lines in this image.

Therefore, the correct answer is B. To show the ridge and opposite sides of the sand dunes.
