Web Science/Part2: Emerging Web Properties/Generative Models for the Web/Evaluating a generative model/quiz

What is true if the statistics of a generative Model match the statistics of the descriptive model?

	The generated data can still be very different from the observed data.
	The generated model is a perfect match of the observed data
	There could be other statistics which we haven't looked at that might not match.
	The model parameters of the generative model could give some reason why we can observe something
	One should try to decrease the number of model parameters
