This is a Parallel Method of Reasoning question.
The stimulus states a conditional rule: complete-24 and thesis → elig-masters
Then it applies the rule to one particular person, Roger: complete-24R and /elig-mastersR
The /elig-mastersR contraposes on the conditional, which implies that for Roger, either he /complete-24 or he /thesis. But we’re already told that he complete-24, therefore it must be true that he /thesis.
All together, the argument looks like this:
- complete-24 and thesis → elig-masters
- complete-24R and /elig-mastersR
- ________________________________________________
- /thesisR
Correct Answer Choice (A)
- mayor-app and council-app → open
- /open and council-app
- ________________________________________________
- /mayor-app
Answer Choice (B) has two problems.
- sci-fic → love or hate
This is the first problem. We need two jointly sufficient conditions. The second problem is that it’s not even clear if the “hate” condition is failed. (B) says, “I do not hate the movie I am watching now.” That suggests the author is reporting to us mid-movie. Like, he’s not even done with the movie yet. So, it’s possible that he changes his mind. The conclusion reinforces this with “probably.”
Answer Choice (C)
- govt-bought or other-bought → improve
- /improve
- ________________________________________________
- /govt-bought and /other-bought
This argument is valid but doesn’t match the form in the stimulus.
Answer Choice (D)
- sale → used or paperback
- saleB
- ________________________________________________
- /paperbackB → usedB
This argument is valid but doesn’t match the form in the stimulus.
Answer Choice (E)
- owe → higher or bankruptcy
- owe and /want-bankruptcy
- ________________________________________________
- higher
This argument doesn’t match the form in the stimulus. It’s also not valid because not wanting to declare bankruptcy isn’t the same as not declaring bankruptcy.
