Would they use a model and why?
When architects want to build a brige they always should use a model because they need to test the bridge, and make it strong enough to resist a strong magnitude earthquake because if they don't they have no idea what will happen to the bridge or they could put a lot of lives in endanger.
* What would be the variables of the model?
The variables of the model would be that they need to think the design of the bridge's columns because they have to come up with and idea of how to make them so the bridge can resist an earthquake. They also need to think the design of the bridge.
