2. Diagnose the problem (if there is one) with the following argument. If there isn’t a problem, defend the soundness of the argument:
P1) John loves nobody.
P2) Nobody loves John.
C) Therefore, there is someone whom John loves who loves John.

3. Which of the following combinations are possible? If you think a combination is possible, provide an example to demonstrate this.
a) A valid but unsound argument.
b) A sound but invalid argument.
c) A sound argument with a false premise.
d) A valid argument with all false premises and a true conclusion.
e) A sound argument with true premises and a false conclusion.
F) A valid argument with exclusively false premises and a false conclusion.

4. Is there a problem with the following argument and, if so, what might it be? Explain your answer.
P1) The country hill is not tall.
P2) The basketball player is tall.
P3) If x is tall and y is not tall, then x is taller than y.
C) Therefore, the basketball player is taller than the country hill.
