Hi Sharon, thanks for reaching out. ' One by one, the rules can be diagrammed as follows.
I -- K L
N -- L
F -- I
M -- F
G -- M
J -- G
H -- J
Now we need to find the rules with variables in common so that we can combine the sequences.
This ends up creating the following
H -- J -- G -- M -- F -- I
-- K
N -- L
It is kind of difficult to show it perfectly through written format on a message board, however what this is showing is that:
H's salary is less than J's, which is less than G's, which is less than M's, etc
Both chains leading to K are unrelated. We have no idea as to whether N is greater or less than any of the other variables in the top chain. All we know that these two chains have in common is that both I and L have salaries less than K.
I hope this helps. Please let me know if you have any other questions.
