Question 2
Choose the correct answer. How does the quality of models relate to the quality of the modeling language used to express them?
A. Model quality benefits from the degree of syntactical and semantic formalism supported by the modeling language
B. The modeling language must be applicable to a wide range of domains of practice in order to produce high-quality models.
C. The level of comprehensibility of the modeling language's abstract syntax directly corresponds to the quality of the models
D. The quality of the modeling language does not influence tin.- quality of the models because the quality of the models depends on the skill and knowledge of the modeler
