Show answer & explanation
Correct answer: B
Answer: Only the conclusions "All folders are drawers." and "All files are drawers." follow.
Explanation:
From the statements we have the chain: all files are folders; all folders are boxes; all boxes are drawers. So every file is a folder, every folder is a box, and every box is a drawer.
"All folders are drawers." follows because folders → boxes → drawers, so every folder is a drawer.
"All boxes are files." does not follow. The statements do not state that every box is a file; they only state that every file is a folder (and hence a box), so boxes may include items that are not files.
"All files are drawers." follows because files → folders → boxes → drawers, so every file is a drawer.
"All drawers are folders." does not follow because drawers are the outermost set in the chain and need not be contained within folders.
