Tade, I don't have access to this question set and am not trained in these specific matters, so you have to be the one who checks my answer :)
Ok here we go, this is as it states about sequences thus an ordered set like the 'alfabethized' set {A, B, C}.
I'll start by saying each letter represents a name so Jazz = J
The 'greater than'-set of rules that make the first order is:
J > O > K > M
The 2nd set of rules make:
L > P > N
However it also mentions P > O, this wil give N and O the 'same unknown weight' as well a place in the first sequence, this make the last piece of the sequence:
P > N or O > K > M
So the correct answer should be B
Hope this helps,
Niels
[EDIT] Tade, I kept thinking about it over dinner, but new logic points arose and it seems quite impossible to me, if the votes are all different as is stated to have more than 3 that can be called 'most popular three'.
