Careful here, Deck. The Justify Formula says that rogue elements are often involved in correct answers, but it doesn't say that every single rogue element must be involved in the correct answer. As noted in the main explanation, there is the idea of the relevant premises to the creating the conclusion. The test makers are plenty smart, and can easily toss in useless information as a distraction. Here's a simple example:
- Premise: A B
Premise: C D
Conclusion: A D
In the example above, the answer B
C would work perfectly, but note how E, which is a rogue element, is irrelevant to the argument. It effectively serves as a distraction inside the problem, but would surely show up in multiple answers.
It's good to think about these problems from the bigger picture, but always keep in mind the test makers have so many avenues of attack you have to be flexible in your thinking.
