Hello @mg123,

The paintings from the art movement fall into two categories.

Almost all: bold brushwork and sharp contrast
The rest: abstract

A key phrase here is "the only ones," which creates the clear divide between these two categories.

We are told that Blue Irises cannot be considered part of the art movement, because it does not have a sharp contrast of light and shadow. However, are there some paintings in the movement that don't have sharp contrast? Yes, the abstract ones! Why can't Blue Irises be abstract? This possibility means that the conclusion cannot be made.

Let's try the negation test on answer choice C: Blue Irises is an abstract painting. This defeats the argument, making C our correct answer.
