Questions & Step-by-Step Solutions

All dogs are animals. Some animals are not pets. Therefore, some dogs are not pets. (2023)
  • Step 1: Understand the first statement: 'All dogs are animals.' This means every dog belongs to the group of animals.
  • Step 2: Understand the second statement: 'Some animals are not pets.' This means there are animals that do not belong to the group of pets.
  • Step 3: Analyze the conclusion: 'Therefore, some dogs are not pets.' This suggests that there are some dogs that do not belong to the group of pets.
  • Step 4: Check if the conclusion logically follows from the premises. Just because some animals are not pets, it does not mean that any of those animals are dogs.
  • Step 5: Conclude that the premises do not provide enough information to support the conclusion. Therefore, the conclusion does not necessarily follow.
