Answer:
FALSE
Explanation:
Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given compound statement are:
4 < 3 and 5 < 10
4 <3 or 5 < 10
not (5 > 13)
4 < 3 and 5 < 10 this statement is false because "and" logical operator required that both operand (4<3) and (5<10) are true. Statement (4<3) is a false statement so this statement is false. "and" operator becomes true when all its inputs are true otherwise it becomes false.
4 < 3 or 5 < 10 this statement is true because "or" logical operator to be true if one of its input is true and false when all inputs are false. so in this compound statement, the first statement is false and the second statement is true. so this compound statement is true.
not(5>13) this compound statement is true because it has "not" operator and "not" operator makes a false statement to true and vice versa. so (5>13) is a false statement, and when you append "not" operator before it, then this compound statement will become true statement, so this is a true statement.
