Matching Drop Down - How to add more options

Thanks both. Yes Ren i also have tried other type of slides, like multiple choice, but my client have a request that there must be 1 question per slide and a lot of answers to select, where just 1 is the correct. So in multiple choice the size of the screen wont allow me to add a lot of choices, Matching Drop Down have the perfect design to add a lot of answers  to select. But there must be a way to do this.
