Using logic to define complex domains with uncertainty fails for three reasons. Match the cause for failure with the explanation below. a. Laziness
b. Theoretical ignorance
c. Practical Ignorance

1. Medical science has no complete theory for the domain.
2. Even if we know all the rules, we might be uncertain about a particular patient or situation because not all of the necessary tests have been or can be run.
3. It is too much work to list the complete set of antecedents or consequents needed to ensure an exception less rule and too hard to use those rules.

Which of the following statements is incorrect in relation to processes: while, strictly speaking, at any instant of time, the cpu is running only one process, in the course of 1 second, it may work on several of them, giving the illusion of parallelism a process is just an instance of an executing program, including the current values of the program counter, registers, and variables processes can be created when an operating system is booted, created by the user, or a running process can create children processes there is a master process, which when started can last forever, and is not killable
