Step 1: Analyze statements
- Statement 1: "All dogs are cats" means every dog belongs to the category of cats.
- Statement 2: "Some monkeys are cats" means monkeys and cats have some overlap.
Step 2: Analyze conclusions
- Conclusion I: "Some monkeys are cats" directly matches statement 2 and is therefore true.
- Conclusion II: "No dog is cat" contradicts statement 1 and is false.
Hence, only conclusion I follows.
