Question 1. Explain clearly why competition synchronization is not a problem in a programming environment that supports coroutines but not concurrency.

Question 2. What is the best action a system can take when deadlock is detected?

Question 3. Busy waiting is a method whereby a task waits for a given event by continuously checking for that event to occur. What is the main problem with this approach?

Question 4. In languages without exception-handling facilities, it is common to have most subprograms include an "error" parameter, which can be set to some value representing "OK" or some other value representing "error in procedure." What advantage does a linguistic exception-handling facility like that of Ada have over this method?

Question 5. In a language without exception-handling facilities, we could send an error-handling procedure as a parameter to each procedure that can detect errors that must be handled. What disadvantages are there to this method?

Answer these questions in details and give examples to support your rationale.
