Answer: A) C) D)
Explanation: I have found the statements that are missing in your question.
A. They frequently show life in the city. B. Their brushwork is very controlled and polished. C. They are done in the style of Realism, showing life as he saw it rather than in an ideal way. D. Critics believed the artwork belonged in an ash can and gave Sloan's group the nickname Ashcan School.
- John Sloan was an American painter and he is known for the urban scenes and neighborhood life in his art and that's why statement A is true, he was showing real life in the city that he lived in, New York.
- Because of the real-life that he was representing in his artworks, statement C is also true, they are realistic and in that case, the style is Realism, nothing is idealized in his artworks.
- He was one of the founders of Ashcan School and the term of that school he didn't like at all because of the critic's beliefs. (D)
In my personal opinion art is a little easier than science since im more on the creative side :)
