@charlenehansen I thought about this too and tried to come up with a few examples. (1) We know that Mary completed the entire project and made no mistakes because she is a responsible manager. OR (2) Since we know Mary is a responsible manager, we can conclude her work on the project is both accurate and complete.
@KatherineDobson Nice! This is right; to validly use the principle while having the concept that someone did act responsibly, "acted responsibly" has to be part of the premise. We can't conclude that someone acted responsibly, but we can start with the fact that someone acted responsibly and conclude something else.
I could be so far off with this - but number 5 threw me because I thought that the answer choice had to follow the conditional logic in the statement. I ruled out C because I thought it was negated but not reversed. Clearly I was wrong in my approach. So this doesn't matter for PSA questions? I'm gonna poo my pants
@TrinityLynn What's the conclusion of C? What's the premise?
The argument does have to validly use the conditional. But I think you might just be thinking about the order of the statements and not about what's premise and what's conclusion.
@Kevin_Lin I'm a little confused as to why C is correct and B is not, on this question. To me, C appears to follow the same pattern except for the concession after the word "for". Can you elaborate further or is there a concept that I should dive deeper into to understand why the two choices are not the same?
I've been answering these questions like they're "most strongly supported" hence the low score... Is it fair to just identify premise, then conclusion, and close the gap?
I have question about last question parallel principle, you elimanited very fast first two, because they not fit in conditional logic if all A are B, its not meaning that all B are A, but I don't see it in this examples...
@Lidiia In Questions A and B, Because and for are premise indicators, so you could rewrite question B into
Premise: Mary first examined the details of his work record and listened to negative reports from some of his supervisors
Conclusion: Mary acted responsibly in firing John
B > A
But because making a reasonable effort to make sure the information is accurate and complete is the necessary condition/superset, it is possible to fullfill this condition without acting responsibly in one's profeesinal capacity.
@Lidiia It took me about the same time. I think taking time with the foundations is a better method than rushing through for the practice, as you may give yourself extra practice time, but will be less able to understand the "why" when you delve into process of elimination. Ultimately, everyone will have their own pace that works for them and there is no "right" way other than the way that works for you
Wouldn't D be incorrect because the "only when" introduces the necessary condition which would not be our conclusion? Don't we need the necessary clause to be the conclusion ?

For Question 5 is it possible to have an AC where they did act responsibly? How would that be worded?

Have you worked through the Conditional Logic Module? That’s going to help with the difference between B and C.

I hate this question type with a passion

is it ok that it took me 3 months just to study all curriculum? and then go in to PT practice? or on average people do it faster?

@EllieBonnette Are you referring to the bus collision problem? If so, we also have to keep in mind the contrapositive.
Premise: I followed rules
Conclusion Should not reprimand me
We'd look for a principle that establishes "If I followed rules, then don't reprimand."
But "If reprimand, then I must not have followed rules" is another way to express that idea.
So "Reprimand only if I didn't follow rules" could be a correct answer. (D) doesn't say that, but the "only if" doesn't automatically make (D) wrong.
@Kevin_Lin Thank you!!
