1. Reconstruct the argument in the following passage in premise-conclusion form: â€œIt is sometimes said that â€˜light is a form of wave-motion,â€™ but this is misleading, for the light which we immediately see, which we know directly by means of our senses, is not a form of wave-motion, but something quite differentâ€”something which we all know if we are not blind, though we cannot describe it so as to convey our knowledge to a man who is blind. A wave-motion, on the contrary, could quite well be described to a blind man, since he can acquire a knowledge of space by the sense of touch; and he can experience a wave-motion by a sea voyage almost as well as we can. But this, which a blind man can understand, is not what we mean by light: we mean by light just that which a blind man can never understand, and which we can never describe to him.

2. Diagnose the problem (if there is one) with the following argument. If there isnâ€™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.
