Syllogisms question 27
Statements:
All files are folders.
Some folders are drives.
No drive is a disk.
All disks are files.
Conclusions:
I. Some folders are not drives.
II. No disk is a drive.
Assuming the statements to be true, which conclusion(s) logically follow(s)?
- Only conclusion I follows
- Only conclusion II follows
- Both I and II follow
- Neither I nor II follows
Answer and explanation
Answer: C. Both I and II follow
Explanation: 'No drive is a disk' converts to 'No disk is a drive', so II follows. Every disk is a file and hence a folder, and no disk is a drive, so those folders are not drives: I also follows.
