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.

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

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

__ __ __ __ __ __ __

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

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.

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


P: A—->B

P: ?

C: ~B—->C
How come the answer isn't: ~X--->B
Both questions are the same or so it seems. what did I miss?
