An engineer made a model of a ship to help him think about how it works he made sure that some of the characteristics of the ships were accurately represented but he did not include all of the ships characteristics in his model is it OK that he ignored some of the ships characteristics ?

It is okay, but only if he represented the characteristics that affect how the ship works, because models need to include the characteristics that are relevant to what is being studied.

It is okay, but only if he represented the characteristics that affected whether the model looks like the ship, because models should look like the things that they represent.

It is okay, but only if he represented the characteristics that people would be interested in knowing about, because models are only used to communicate information to others.

It is not okay that he ignored some of the ship's characteristics. A model should be like the object it is representing in every way possible.
