Questions & Step-by-Step Solutions
All cats are animals. Some animals are dogs. Therefore, some cats are dogs. Is this conclusion valid?
Correct Answer: No
Step 1: Understand the first statement: 'All cats are animals.' This means every cat is included in the group of animals.
Step 2: Understand the second statement: 'Some animals are dogs.' This means there is at least one animal that is a dog, but not all animals are dogs.
Step 3: Analyze the conclusion: 'Therefore, some cats are dogs.' This suggests that at least one cat is also a dog.
Step 4: Check if the conclusion logically follows from the statements. Since we know all cats are animals and only some animals are dogs, we cannot conclude that any cats are dogs.
Step 5: Conclude that the reasoning is incorrect. The conclusion does not logically follow from the premises.
