An architect is designing a house. He has made a set of floor plans and has also used cardboard to make a small-scale version of the house. Which of the following is TRUE?

1. The small-scale version of the house is a better model than the floor plans because the more a model looks like the object it represents the better model it is.
2. The small-scale version of the house and the floor plans are both equally good models because they both are representing the same object.
3. Either the small-scale version of the house or the floor plans could be a better model depending on what model will be used for.
4. The floor plans are better models than the small-scale version of the house because models have to be different from the objects they represent in some way.
