Help With A Tricky Logic Problem (multiple choice) Okay everyone, I contacted a logic professor from UNC who formerly worked at Yale and his response was that, in modern logic systems the answer is "D" and that only in outdated, Aristotelian categories it's "E", but that those traditional systems haven't been used since the late 19th century.
Conclusion: the answer is "D" and Tim Wood is a vampire no younger than 122 years old.
