How can I bring objects through to another slide based on state?

Each slide is like its own webpage, so one slide can't really access objects from another slide. However, you could try a few options.

1. The slide master, and its layers, can display on any slide. The master slide displays below your current slide objects, while the master slide's layers display above. You could make layers on the slide master, each containing a single statement, and then set up triggers on the slide master that could display one or more of those layers. Set each of those layers to not hide other layers. That way, they can all be visible at the same time. This approach would be good if your statements are complex, including text, shapes, images, formatting, or animation.
2.  If your statements are just text statements with basic formatting, you could assign each statement to a text variable. Then, on your final slide you can display all of the relevant variables inside a set of text boxes using the %{variable name}% shortcut in your text box string.
3. You could also track the selected statements with variables and reproduce all of the possible statements on your final slide (in layers or on the timeline). Based on the selection variables, you can then make the statements visible as layers or unhide them on the timeline for display.
