@EthanSegerman this is where tactics on test day become important. Imagine seeing this at Question 21.. you still have more questions to go through, this would be a good one to skip and come back to.
Indeed, KY even says in previous lesson that unless you have a good grasp on the foundational skills to probably outright avoid these questions.
I actually despise when the answer choice is E. I'll be reading through each answer panicking like "I don't think this is it, but I'm getting to the end and what if the last answer is wrong!?!?"
Can someone confirm that this is why answer choice A) is wrong? I understand that E) is a much better match for the stimulus, but I'm not very confident in my reasoning for eliminating A).
the stimulus says: A or B. not B. therefore A
answer choice A) says: A or B. A. therefore not B.
I see that the structures are different between the two, but at the same time, the general idea is kind of the same
However, A) is flawed because confirming A is not enough to exclude B. The stimulus (and this answer choice) did not say "either A or B, but not both", so in theory, they aren't mutually exclusive. If we eliminate one of the options, say A, then we know it's for sure B because one of the two must occur. BUT confirming one of the options is not enough to say that the other does not occur.
@AudreyGilmour I struggled with this, too. I think you were right to highlight the word "either," which I think does imply exclusive or: "either A or B, but not both." In an exclusive or situation A -> /B.
With this in mind I think answer candidate A would be a fine choice if answer candidate E was not also an option.
I think A is logically very similar to the reasoning in the stimulus (and I think it's sound reasoning with an exclusive or), but it is certainly not MOST similar when compared to E.
I got this question wrong because I didn't intrepret the stimulus correctly. I understood that it was an A or B scenario (expensive or familiar, but for whatever reason, I didn't pick up on the fact that the prizes being equally unfamiliar is equivalent to saying 'Not B'. Because I didn't realize this, the conclusion 'choose A' really didn't make sense to me - it seemed like an arbitrary decision. Needless to say, I couldn't find an answer choice that matched my flawed understanding of the stimulus :(
#help I don't understand how answer choice B confused a sufficient condition for a necessary condition. Wouldn't the "or" in B be one that does NOT include the option of both, since one cannot go on both rollercoasters for their first ride?
So based on that, I would have thought that /rocket --> mouse works but so does mouse --> /rocket.

Got it but I was like 57 sec over
DANG IT I GOT IT RIGHT BUT I HAD TO PAUSE TO GET A FLY IN MY ROOM SO I WAS A 2 MINUTES OVER
@ManusWeber thanks for letting us know glad I'm not the only one oversharing
okayy, i like this lil section
7 seconds over LETSGOOO
These types of questions are actually enjoyable in my opinion to do! I got it correct :)
Honestly the cost of this course is worth it for this lesson alone, LFG! I was so bad at this type on my diag test. Now I'm knocking it out!
@BrandonSchittone
Totally agree. The flaw 'cheat-sheet' before was a big one for me too. It really nailed down some of that vocab.
Was killing it until this question WTF
UGHHHHHH
It takes so long to do these questions wtf

Maybe I should try to disregard this, but I've had three answers that were E in a row, which really messed me up lol
Now I know why Winnie the Pooh Bear never had a fox character....
these take forever to do jeez
I have been able to diagram these questions correctly thus far, however, my average time has been 5.5 minutes (sigh)...
If this persists, is it really worth sacrificing 3-4 questions we could be working on in the actual test, if we encounter parallel questions?
@bcn no. You should guess and move on if you don't see the answer immediately.
I've been organizing the content of the stimulus and then shallow-dipping this way using colour and it's been helpful:
im not sure why the the trigger for the stimulus is not choosing B means he will choose A, rather than he chose A not B like it pretty much stated...
@KUROUSHFAIZRAFATIAN
The wording conceals the simplicity of the question:
X or Y.
/Y, so X.
Choose expensive prize (X), or choose familiar prize (Y).
Both prizes unfamiliar (/Y), thus choose expensive (X).
Same with the answer:
Double back (X), or flee for cover (Y).
No cover (/Y), so double back (X).
i got this answer correct by sheer luck... i panicked #imcooked
I thought of it as
P: A or B
P: ~A
Conclusion: B
It is essentially saying either you're red or blue, you're not blue, therefore you're red.
I found this easier to comprehend, and it is also logically equivalent to what the lesson wrote (~A --> B)
But in my case, I guess it also accounts for
~B --> A
This could be an easier way to understand this/map it out.
There should be a short Lawgic review section before this unit
These questions have me internally screaming.
This question would have been so much easier if Miyoko would just show a little academic curiosity.
I actually despise when the answer choice is E. I'll be reading through each answer panicking like "I don't think this is it, but I'm getting to the end and what if the last answer is wrong!?!?"
Makes me freak out

Thanks in advance!

Using the shallow dip technique has really helped me get most of these questions right.
