Answer 1

The prolog predicate for comparision of values x and y where x less than equal to y will be x<=y

In prolog the period means stop as in prolog all sentences must end with a period.

For everything that is not in the knowledge base and cannot be inffered from the knowledge base prolog assumes that it is false this is called closed world assumption because in prolog if it cannot prove something is true it assumes that it is false it is also known as negation as faliure.
