Answer 1

The clock will slowly become quieter and will ultimately fade from view.

Answer 2

The clock will slowly become less visible, until you can only hear it.

Answer 3

As the air is removed from the space around the ringing alarm clock placed under the glass jar, the sound will become fainter. This is because sound waves require a medium (such as air) to travel through. Without air molecules to carry the sound waves, the sound will become quieter. However, the appearance of the clock will not change as it is independent of the presence or absence of air. Therefore, the correct answer is: "The appearance of the clock will not change, but its sound will become fainter."
