The only way other objects can access a given object’s data is through one of the target object’s __________.

What is the primary difference between event-driven simulators and script-driven simulators?

a) Event-driven simulators are controlled by events that occur according to probability distributions, whereas script-driven simulators are controlled by data carefully manipulated to reflect the system's intended execution environment. b) Event-driven simulators are controlled by events made to occur to reflect the system's intended execution environment, whereas script-driven simulators are controlled by data carefully manipulated based on probability distributions. c) Event-driven simulators are controlled by traces of events that occurred in other systems built for a similar execution environment, whereas script-driven simulators are controlled by a script of events that evaluators predict is similar to one that would occur in the system's intended execution environment. d) The only difference is that event-driven simulators are controlled by events, whereas script-driven simulators are executed without any input regarding events.
