If all mammals have lungs and some whales are mammals, can we conclude that some whales have lungs?

If all mammals have lungs and some whales are mammals, can we conclude that some whales have lungs?

Step 1: Understand that all mammals have lungs. This means every single mammal, without exception, has lungs.
Step 2: Recognize that some whales are classified as mammals. This means there are certain whales that belong to the group of animals known as mammals.
Step 3: Since all mammals have lungs, and we know that some whales are mammals, we can say that those specific whales that are mammals must also have lungs.
Step 4: Therefore, we can conclude that some whales have lungs because they are part of the group (mammals) that always have lungs.

Logical Deduction – The ability to draw conclusions based on given premises.
