If the statements 'All cats are mammals' and 'Some mammals are not dogs' are true, which of the following must also be true?

Step 1: Understand the first statement: 'All cats are mammals'. This means every cat belongs to the group of mammals.
Step 2: Understand the second statement: 'Some mammals are not dogs'. This means there are certain mammals that do not belong to the group of dogs.
Step 3: Combine the information: Since all cats are mammals, and we know that some mammals are not dogs, it is possible that those mammals that are not dogs could include some cats.
Step 4: Conclude: Therefore, it must be true that some cats are not dogs, because all cats are part of the mammals, and some of those mammals are not dogs.
