Answer:
D)One big superclass can be used instead of many little classes.
Explanation:
Inheritance could be described as getting new class on another existing class with almost same execution,
inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.
The advantages of using inheritance includes but not limited to
✓ Code that is shared between classes needs to be written only once.
✓Similar classes can be made to behave consistently.
✓ Enhancements to a base class will automatically be applied to derived classes.
After a group sets a project schedule, members should be prepared to complete a study-time survey to prove they can do the work.

Answer:
should there be 'except' in the question?
Answer:
the CPU utilization decreases as the degree of multiprogramming is increased.
Explanation:
The fundamental concept is that allocating a process with too few frames causes too many and frequent page faults. This implies that the CPU does not perform any useful work and thus its utilization would decrease drastically. In this case, the long-term scheduler, in a bid to improve the utilization of the CPU, would load more processes into the memory so as to increase the extent of multiprogramming. As a result, there would be more decrease in the utilization of the CPU, leading to a chained reaction of higher page faults, which is then followed by a corresponding increase in the multiprogramming degree, usually known as thrashing.
