IV. Composition
As pets, cats and dogs have their own advantages and disadvantages. Cats are independent and clean while dogs are loyal and warm. On the other hand, one may also argue against either of them by holding that cats are rather detached and dogs mean a lot of cleaning up for the owners. If you are asked to choose your pet only between dogs and cats, which will it be? Please provide an argument to support your choice.
                                                     Write your answer in 150~200 words.
                                                            This is the end of the test.
