Instructions General Instructions:
Quiz 7 consists of 5 questions. You are given 1.5 hour (90 minutes) to complete this
quiz.
Question 1:
Determine the truth value of the given propositions in system RP.
Questions 24:
Determine whether the given propositions are tautologies, contingencies, or
contradictions in systems P, RP, and Łucasiewicz’s threevalued logic.
Question 5:
Determine whether the given arguments are valid or invalid in systems P, RP, and
Łucasiewicz’s threevalued logic.
IMPORTANT:
Please note that the quiz must be finished and submitted before the corresponding
deadline as in the schedule, not just started once the deadline is reached, the system
will automatically stop the quiz and you will no longer be allowed to continue with the
quiz (so you might lose your points for the quiz). Also, when you are done, make sure
you press the Submit button unless you do so, the quiz may not automatically be
submitted to the system (and you risk losing all the points for this quiz)!
If, while taking the Quiz, you experience any technical problems which prevent you
from completing the Quiz, you must immediately report your issue to the ITpeople
responsible for the technical issues (not the instructor!) by following the "DL Help
Desk"

current situation and they will then send their report to me, the instructor, with all the
relevant information. If not reported to the DL Help Desk, I, the instructor, will not be
able to verify any issues with the Quiz, and, as such, will not be able to change your
grade or give you any other attempt to finish the quiz.
Suppose the propositions A, B, and C are as given below. Suppose further that A, B, and C
are all true. Determine the truth values of each of the following formulas of (nonclassical
relevance logic) system RP.
A = "Socrates was a philosopher", B = "Socrates lived in Greece", C = "Einstein was a
physicist":
Question Correct Match Selected Match
B → (A V ¬C) 2. False 1. True
¬(A & B) C 2. False 1. True
¬(B A) (B ¬C) 1. True 1. True
All Answer Choices
1. True
2. False
Response Topics mentioned in the atomic propositions:
Feedback:
Topics in A: "Socrates", "being a philosopher";
Topics in B: "Socrates", "living in Greece";
Topics in C: "Einstein", "being a physicist".
Question 1.1:
Topics mentioned in (the molecular proposition) ¬C: "Einstein", "being a
physicist" [same as in C].
So, A and ¬C are not related, i.e., ~R(A, ¬C), since A and ¬C have no common
topic.
So, (A V ¬C) is False no matter what the truth values of the overall formula's
constituent parts are, i.e., no matter what the truth values of A and ¬C are.
Next step:
Topics mentioned in (the molecular proposition) (A V ¬C): "Socrates", "being a
philosopher", "Einstein", "being a physicist" [the union of topics in A and in ¬C].
So, B and (A V ¬C) are related, i.e., R(B, (A V ¬C)), via "Socrates" and "being a
philosopher".
