First, watch that first premise. It's L (Large fund) --> M (NOT run). That's why C doesn't have to be true. The second line of premises is only triggered if he DOESN'T have a large fund. If all we know is that L has a scandalous record, we don't know whether M runs or not. It depends on whether he has a large fund.
As for your second line of premises, notice that we don't actually have "M (win increase) --> M run." What the premise tells us is just that a scandal would increase her chances and lead her to run. It doesn't say anything about whether other things that would increase her chances would lead her to run. It also tells us that if his record is clean, she will definitely not run. So we have this:
Large fund? Don't run.
Small fund? Check for scandal.
No scandal? Don't run.
Scandal? Run.
So she will run if we fulfill the conditions of SMALL FUND + SCANDAL. She won't run if either of those conditions is not met. That means we have one conditional leading to RUN and another leading to NOT RUN.
small fund AND scandal --> run
large fund OR no scandal --> don't run
D violates the second conditional, so it must be false.

Hello,
MartyMurrayDmitryFarbercan an expert help with this Q,
The given premises can be paraphrased as -
L (Large fund) --> M (runs)
L (small fund) --> scrutinize --> scandal --> M (win increase) --> M (run)
L (small fund) --> scrutinize --> no scandal --> M (not run)
isn't (C) "must be false"
because if A --> then B
here scandal (A has already occured) , but they are saying M running (B) hasn't occured, so isn't this contrary to the premise given
with (D),
we know A (win increase) --> B (M runs)
but not A (win not increase), can be B (M running) or not B (M not running)
Please if someone can help

Amy McConnell is considering running for election against the incumbent, Gregory Lutz. If Lutz has a large campaign fund, then he is already far ahead, and McConnell will not run against him. If Lutz does not have a large campaign fund, McConnell will scrutinize Lutz’s record for any hints of scandal that she could use against him. Anything of a scandalous nature would increase McConnell’s chances of winning, and she would campaign for election. If Lutz has a clean record, however, McConnell will not run against him.
Given the information in the passage, which one of the following must be false?
(A) Lutz does not have a large campaign fund, and McConnell does not run against him.
(B) Lutz’s record contains items that would increase McConnell’s chances of winning, and she runs against him.
(C) Lutz’s record contains scandalous items, and McConnell does not run against him.
(D) Lutz’s record contains nothing that would increase McConnell’s chances of winning, and she runs against him.
(E) Lutz has a large campaign fund, and McConnell does not run against him.
