This is a must be true stimulus - with an "except" tied to it, "must be false"
Stimulus:
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.
After reading the stimulus it is clear that certain conditional relationships exist:
1) If Lutz has large fund... -> Then McConnell will not run against...
2) If Lutz does not -> Then McConnell will scrutinize
3) If Scandalous info -> Then increase McConnell's chances of winning (Not completely sure if I should be capturing this one)
4) If Lutz clean record -> McConnell will not run against
The question stem is looking for an answer that is FALSE; so the answer choice will be in disagreement with the conditional reasons above
Question Stem: 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.
This answer choice is wrong.. if Lutz does not have a large campaign fund McConnell will "scrutinize," if there is no scandalous info, McConnell will not run against; so this statement could be true
(B) Lutz’s record contains items that would increase McConnell’s chances of winning, and she runs against him.
As per the conditional statements above: this could be true, if there are items that increase McConnell's chances it is possible the items are scandalous, which is why she is running against him - so this answer choice is wrong
(C) Lutz’s record contains scandalous items, and McConnell does not run against him.
Before McConnell assesses Lutz's record, she will consider the size of Lutz's fund, so this answer choice is wrong as it is possible that McConnell has a large campaign fund and is already a step ahead of McConnell despite the scandalous information/items
(D) Lutz’s record contains nothing that would increase McConnell’s chances of winning, and she runs against him.
This answer choice is correct, and it must be false. If Lutz's record contains nothing that would increase McConnell's chances, and McConnell FIRST bothered to scrutinize Lutz because he did NOT have a large fund, there is no reason why McConnell would run against Lutz if he has a clean record (given his small fund).
(E) Lutz has a large campaign fund, and McConnell does not run against him.
This is true based upon the conditional statements I listed above.
