Answer:
Models may be oversimplified.
Step-by-step explanation:
The problem with the model is definitely this, that they are not fully self explanatory. You are certainly going to find that not all the information can be fetched from them. And hence for the complete information one needs to wait for the project to take its real shape. And only then we can find out the complete details of the project. Hence, the above answer. Various natural phenomenon can be missing from the model due to oversimplification. And hence most complex aspects of the system remains hidden, till the model is transformed into a real project. The scientific observations are always described the best way, and the model is certainly up with all the aspects of an object. Also, they are highly accurate. Hence, the above answer.
