For the first question, the answer is the flowers because there is a variety of them that further illustrates the recurring differences of line, shape, texture, value, color. For the second question, the artist uses a variety of line because there are many marks with length/direction, made on a surface by a moving point on the image. For the final one, I think the answer is value and shape because value refers to the lightness or darkness of achromatic/chromatic media, while shape is <span>defined by other art elements such as line, color, value, or texture. It can take on the appearance of solid three-dimensional forms through shading and other devices.</span>
In my opinion, its what the artist is trying to write ''story wise''. Kind of like a comic book accept done all pretty. I can't tell you a ''correct'' answer of this type of question but i hope you get the main idea.
