Homework questions on December 2000: #1 and #5
On the homework from December 2000 I am having trouble understanding why #1 cannot be answer choice E and is C instead? I guess I am confused with the placement of V.
Also, can you explain why the answer to #5 is C? This was not my original answer and I wanted an explanation for why V is not fourth.

@Reina,
Thank you for your question. Could you clarify which game you are referring to? The game that appears attached to this question is a law firm partners game.

Yes this is the December 2000 game from the sequencing games section

@Reina,
Thanks. The game requires us to rank 7 TV programs - H J L P Q S V. The following rules apply: (1) J & L are each less popular than H. H> J H >L
(2) J is more popular than Q H > J >Q
(3) S & V are each less popular than L H > L >S H > L> V
(4) P &S are each less popular than Q H> J> Q > P H> J> Q> S
(5) S is not 7th
__ __ __ __ __ __ __ ~S
Taken together we have the following chains: H> J> Q > P H> J> Q> S H > L >S H > L> V
The reason answer choice (E) in question 1 is incorrect because it violates rule (5) - S cannot be #7,
The correct answer to #5 is (B). Question 5 asks us if Q is more popular than L than each of the following must be true EXCEPT:. Let's add this rule to our original diagram:
H > J > Q > P L> S V
We can infer that H must be #1, J -#2, Q -#3 - thus we can eliminate (A), (D) and (E). We can also infer that either L or P must be fourth because S and V must go after L per rule (3). Since the highest rank L could take is #4, it is not possible for either S or V to be fourth, thus we can eliminate (C) - remember, it is an EXCEPT question. The correct answer is, therefore (B) since L could be but not must be fourth as P could be fourth instead.
Let me know if this makes sense or if you have any further questions.

Hi,
I have a question on #7. The correct answer is C I picked E. While I see how C could be the answer, I still can't find my error in my answer of E. Can you explain to me why E is not correct? I want to understand where my reasoning is wrong.

@cglee, happy to help!
(E) lists the sequence H, L, V, J, Q, P, S
This is invalid because S is placed 7th. Rule #5 tells us that "S is not seventh." Therefore, (E) is incorrect because it violates Rule #5.
Does that make sense? Please let us know if you have any other questions!

P: X—->A
P: ?
C: ~A—->B
THE ANSWER IS : ~B—->X
BUT WHEN THE NEXT PROBLEM IS:
P: A—->B
P: ?
C: ~B—->C
THE ANSWER IS: ~A—->C
How come the answer isn't: ~X--->B
Both questions are the same or so it seems. what did I miss?
