On what factor does correspondence between climate models and the real world depend? 

A)  on the design and assumptions of the model 
B)  on organization 
C)  on qualifications of data entry personnel 
D)  on positive feedback

The correspondence between climate models and the real world depends on the design and assumptions of the model. The models are based on mathematical equations and require input data that must be processed and interpreted correctly. Therefore, the accuracy of the models depends on the assumptions made by the researchers who design them and the availability and quality of observational data used to create and validate the models. Organization, qualifications of data entry personnel, or positive feedback are not the main factors that determine a model's ability to correspond to the real world.
