@KevinLin Ok thank you, so takeaway is to (if you have time) break down all the parts in the stimulus to see if the flaw is there

I'm kinda confused as to why we need to check for flaws between intermediate conclusion and premises AND the Main conclusion and intermediate conclusion. (Kevin says that @ 20:08). Is looking at flaws between the premises and main conclusion not enough?

Is there a specific lesson on percentage/whole? I struggle with it quite a bit, it's not intuitive to me

Question for you guys: so I just completed the LR curriculum and am going through these as a high-level refresher. I got 60% on this drill. Is it worth drilling these more? Do I aim for perfection... keep practicing... or move on?

1. Does the similarity or analogous case the argument presents actually support the conclusion?

I don't think I get how this is supposed to help us.

Wait but how is "The time that it takes to have a pizza delivered may be longer than it takes to cook a complete dinner." not an example of the cost outweighing the benefit? What am I missing? #help #help

JY says it's because we only take into account time? Huh

what are we all smoking

So does this mean negation is something that we worry about?

So if I understand correctly, there is a suf/nec flaw AND a causal flaw, but the correct ac only talks about the causal flaw?

@hannahhuynh ahh gotcha, but you're using an ipad to take the notes right?

fuming rn

What type of reasoning is at play here?

The explanation for AC C makes no sense to me. This is how I interpret it: To negate “not many x have been transferred to y” would be to remove the not, so it would be “many x have been transferred to y”, but since “many” is logically soft, we treat it like a some relationship. SO, SOME films from the earliest years of Hollywood have already been transferred to acetate.

Why does JY's explanation say that "it’s good that there (C) guarantees a “most” intersection." huh??

Sooo... is the reasoning here cost-benefit? I approached it that way...but didn't clock the prescriptive/descriptive gap it seems

When JY says I'm surprised the test writers didn't add: "disposal of tanning waste produced with biological catalysts costs roughly the same per pound as disposal of waste produced with the conventional process. That answer would be sufficient (strong) but not necessary."

I don't get how I'm supposed to catch that. Because if we negate the statement, (/roughly the same per pound) meaning it costs slightly MORE per pound of bio vs. pound of chem, wouldn't that be DETRIMENTAL to the argument? Because then we cannot say that bio is cheaper.

@hannahhuynh are these your notes? how are you taking them digitally? is this like an ipad. Looks helpful

@KevinLin No! From that, we could only prove that if /B, then /A. OHHH so A is not reachable for that reason?

Can someone explain how we are supposed to know this is a bi-conditional EVEN after mapping out:

ER --> eligible

/ER --> /eligible

I don't think I'd be able to recognize that this is a bi-conditional

"Now consider two conclusions: access is justified versus access if not justified. Which conclusion is reachable via the first rule? Access is not justified. That is a reachable conclusion. To reach it, we just need to trigger the rule contrapositively."

Can someone explain why the justified conclusion is not reachable if it's the suff condition? 

bruh I am actually the 1% that choose D. brutal lmao

@ActuallyJozu thank you so much for your response!! I WISH U ALL THE BEST TOO! YOU GOT THIS

If i got 3/5 on this, should I keep doing drills or better to move on and come back to these question types later?

Can someone pls explain this to me : "Some parrots that can learn to speak a few words and phrases show tremendous affection for an owner who raised the bird from a chick."

HOW is this a valid inference that can be drawn? it doesn't follow the "most before all" rule

@ja4718b761 Right, i'm also confused about this cause isn't or mean "one of the other, or both"???

@AlizaGGG yes agreed, it sucks
