"a. Socrates is Mortal" is false. Socrates was mortal until he died, at which point he ceased to exist.

"a. Socrates is Mortal" is false. Socrates was mortal until he died, at which point he ceased to exist. Which leads us to another logical dilemma: How can you talk about something which does not exist?

How can you talk about something which does not exist? That sounds like a question for a priest, minister, rabbi, or mullah.

People talk about things that don't exist all the time.
And there is a difference between something that has existed but doesn't exist now. If a tree falls in a forest and no one was around to hear it, did it happen?
If humans don't know about something, does it mean it doesn't exist?
That means, my friend Bob, in this puzzle, that things must be known to exist and if it exists only in the mind, then things depend on a human mind to make it real. Which, if I remember correctly, that doesn't agree with you or Objectivism.
As far as the Tetrad, tricky wording can con anyone anytime unless you use critical thinking and logic.

C and D are wrong.
c. A man is mortal only if there is a future time at which he dies.
Mortal means "subject to death". That is, if something can die, it is mortal. The when doesn't matter at all – past present or future. (Except to the man. LOL)
d. A man cannot die twice.
Depends on how you define “die”. And, in any case, irrelevant to the definition of “mortal”. All “mortal” beings are either already dead, in the process of dying, or will die in the future. Dying more than once, whatever the definition of “death”, doesn’t remove mortals from the system, just changes the date of final death.
Word games can be fun for the whole family. 8->
