Bill earns more commission than does Sandra. But since Andrew earns more commission than does Lisa, it follows that Bill earns more commission than does Lisa. Any of the following, if introduced into the argument as an additional premise, makes the argument above logically correct EXCEPT:

A.Andrew earns more commission than Bill

B.Sandra earns more commission than Lisa

C.Sandra earns more commission than Andrew

D.Sandra and Andrew earn the same amount of commission

E.Bill and Andrew earn the same amount of commission OA later after discussion..

I'd write down everything with some pointers:

Original argument: Premise 1. B > S Premise 2. A > L Conclusion. B > L

A. A > B - this does not invalidate the argument. You could have A > B > L, which would use up "A", Premise 2 and Conclusion.

B. S > L - this one is good too. Since we have B > S (Premise 1), adding S > L means that B > S > L, which ultimately leeds to the conclusion.

C. S > A - good as well. If B > S (from Premise 1) and S > A (from C) and A > L (Premise 2), you get that B > S > L, which again takes you to the conclusion.

D. S = A - works. It's basically the same as with C.

E. B = A - it's basically A all over again.

I'm getting that all of them are correct. I'm making a mistake somewhere, maybe someone else can help...

Original argument: Premise 1. B > S Premise 2. A > L Conclusion.B > L

1. A > B - We can have A > B > S by this and Premise 2 says A > L. We cannot prove that B > L via this. Correct answer

2. S > L - From Premise 1 we know already know that B > S. So S > L makes argument logically correct

3. S > A - From Premise 2 we know A > L and from Premise 1 we know B > S. Therefore B > L makes the argument logically correct

4. S = A - From Premise 2 we know A > L. Therefore if S = A then we can say that S > L. Premise 1 says that B > S. Hence makes the argument logically correct

5. B = A - Premise 2 says A > L and if B = A we can say that B > L which makes the argument logically correct.

in ascending order S < B L < A (it follows that L < B) then definetly Bill must be earning more than Andrew, only then we can decide Bill also earns more than Lisa so L < A < B

A. B < A this is false , as per our derived result

B. L < S , possible

C. A < S (doesnot violate S B) , possible

D S and A same amount (till within B) so possible

E B and A same amount possible, they are top two earners, so conflict

A. andrew earning more than bill meaning bill and lisa earn less than andrew, doesnt say anything about bill and lisa

bill>sandra andrew>lisa

1. B>S 2. A>L

is B>L ?

A. Correct answer

it says A>B, so we have two options

A>B>L or A>L>B

So, this option is insufficient to conclude the answer (whether B>L or L>B), that's what question asks. We have to choose one option that can't complete the logic.
