What is one of the problems with using operational semantics for complete formal semantics descriptions?
- The sequence of state changes is too easy to analyze
- The storage of a real computer is too small and simple
- The intermediate language is too high-level
- The individual steps in the execution of machine language are too small and numerous (correct)
