To accurately determine which two statements best express the effect of the author's use of diction, one needs to analyze the specific diction used in the text referred to in the previous question. However, based on the options provided, you can select the statements based on the tone and imagery typical of the words used.
If the diction includes vibrant and overwhelming descriptors (like "brash" and "garish"), then A and C might be appropriate.
If the diction conveys pleasant and positive feelings (like "warm and inviting" or "beautiful and comforting"), then B and D would be suitable choices.
If the diction conveys negative and alarming feelings (like "frightening and horrible"), then E would be appropriate.
Ultimately, the answer depends greatly on the actual text's diction. If you can provide the specific diction or text in question, I would be able to assist you more accurately in selecting the appropriate statements.
