can someone break down necessary condition vs sufficient for me again in simple terms? I will feel confident understanding it just to get it wrong again
so far i have a perfect score on formal flaw questions but a zero on informal flaw questions... what am i doing wrong? why isnt informal makes sense to me the way formal is?!
#help okay I am getting tripped up because I feel like so many of these are simply “confusing suf. for nec.”
For ex. this question and like two questions ago - I was choosing A. Then consciously decided to change my answer, thinking there is no way there is this many confusing suf. for nec. and maybe I am being tricked.
#Feedback. So the flaw in this question is that the argument didn't Negate B first and then negate A. But instead Negated A and then B, which is not how sufficient/necessary rules work.
This entire section has helped me realize just how important it is to avoid the sufficiency-necessity confusion. Thankfully, it's starting to stick out like a sore thumb now. Thanks, JY!
This unit was not too difficult imo. Though I went over target time because I was between A and C but glad I noticed A was literally what the whole argument was concluding.
#help - I went from getting almost every question wrong in the first half of this unit, to now breezing through the last five questions no problem, correct and on target. what does that say about me? the first half of these questions were casual logic and assumption gaps, right? should go back and relearn that material? advice please!
This is what is helping me solve difficult / lengthly questions. Instead of putting things into an equation form, try to vizualize the content as and when you read it. For eg.
A development company has proposed building an airport near the city of Dalton. I'm from Bangalore, India and Brigade is a popular development company. So I visualize this line as, Brigade Group is given a mandate to build some new airport in a nearby city.
If the majority of Dalton's residents favor the proposal, the airport will be built. If the majority of the residents of that nearby city say 'yes', airport will be built. But here, I'm thinking - so what if they say no? Airport may still be build if let's say, a bill is passed in the parliment specifically for the construction of this airport.
_
However, it is unlikely that a majority of Dalton's residents would favor the proposal, for most of them believe that the airport would create noise problems. _ Ok, so now I don't know whether airport will be built or not (because I don't know any other factors such as bill in the parliment etc. that may trigger the construction of airport).
Thus, it is unlikely that the airport will be built. NOO! You have just eliminated one condition that could've trigger airport construction (resident's saying no)., but what about the other considerations? How did you assume that none of those factors comes into play here?
Now, hunt for AC that says, confusing sufficient for necessary.

Does anyone else feel like this?
these flaw questions eating me uppp :(
mightve only been 3 seconds under, but we got it right baby
Idk how to explain it but I just felt in my soul that there was a sufficient necessity confusion and went with A LMAO.
#Feedback. So the flaw in this question is that the argument didn't Negate B first and then negate A. But instead Negated A and then B, which is not how sufficient/necessary rules work.
Is this thinking correct?? Thanks!
55 seconds off target but i DONT CARE i got it right ive been struggling with this wholeeee section ahhhhhh

Got it in under a minute 😮💨
7 seconds lower than target after struggling this whole unit <3
getting faster, 12 seconds slower than target and correct
Just to confirm the initial logic of the premise in the stimulus...
ignoring the unlikely/likely language the premise is:
majority favor → built.
so would it be correct to conclude, /built → /majority favor?
Just because something is sufficient doesn't make it necessaryyyyyy!!! ; )
Screw this test.

maybe my conditional logic is flawed but I just don't know how to parse what is sufficient and neccasry in these long texts. any tips ?
