which of the following statements describes an advantage of using a computer simulation to model a real-world object or system? which of the following statements describes an advantage of using a computer simulation to model a real-world object or system? simulations allow us to test real-world events without the cost or danger of building and testing the phenomena in the real world. computer simulations model real-world objects and systems perfectly, without making any simplifying assumptions. computer simulations are easy to debug. computer simulations run very quickly, regardless of the level of detail of the model.
