TIL:
While people usually use the word "obtain" to mean "to get" something (e.g., “to obtain a passport”), it has a second, more formal meaning in English. When used without a direct object at the end of a clause, "to obtain" means "to be prevalent, customary, or in effect."
I got it right, but only through elimination. Had no idea "did not obtain" could be used like that.
Me: "Oh B is good"
JY: "This one is obviously wrong"
Me: "Oh :("
Me: "Oh yeah C better, B was bad"
JY: "C is also wrong"
Me: "..."
D is correct because its accurate, and the others are wrong because it isnt.
Ah now I get it!
@StanHolt nah. A large amount of people struggling does not mean its poorly explained. It seems a large amount of people are simply forgetting that "the only" is a sufficient condition indicator and "only" is a necessary condition indicator. That is not the fault of the curriculum. Its a failure of the students. And I say that as someone that is in the group that forgot. Its ok
@Steffy I don't think inspiring confidence is a goal. Its to demonstrate the skills and thoughts needed to get these right. Imagine if you got all of the questions right (because they are easy ones), and then take a test and get a ton wrong, because all you ever learned on was easy questions. That would be a much worse outcome
Was expecting something about shape of the fin being relevant to hunting style. Maybe they have those fins because they migrate over long distances, yet they are still ambush predators for hunting. The fins may be for migration, not hunting style.
I think it could be useful to add space repetition drills for some things. The two I can think of off the top of my head are:
the "indicator words" (sufficient, necessary, negate-sufficient, negate-necessary)
identifying question types
I did some SR myself with flashcards, but the word set is limited as I just picked from the most common ones, and the ID question types is hard to do physically without a lot of work. Being able to easily and effortlessly id indicator words and id question types is such a hack to speeding up and removing analysis exhaustion on the small things.
I recently did https://7sage.com/lessons/logical-reasoning/sufficient-assumption-questions/skill-builder-logical-reasoning-question-stems-first-half and wish I could just hit 20-30 of these a every other day or so until its second nature.
@AdeeshaSenanayake "if you were to negate it, it would directly attack the conclusion"
Oh thats a really strong way to look at it. I was thinking something like "isn't the stim already taking the data to be correct as an assumption?"
I ended up picking D from POE anyway, but I like your way of thinking about it
@SavannahMiller Read "cannot reliably determine" as "is not always accurate" which reads as "is sometimes inaccurate". And read "highly susceptible to inaccuracy" as "usually inaccurate".
"usually inaccurate" meets the burden of "is sometimes inaccurate".
The writers used quantitative sets without using always/usually/sometimes/many/some/etc. You have to read in those qualifiers.
What does "cannot reliably determine" mean? Well it means that at least some of the time, we cannot be accurate. And so on.
@JZ123 Its starting to click for me "Find the Missing Bridge".
P: Photographers express their worldview.
C: Photographs are interpretations
Missing bridge must be something like "Express Worldview == Interpret"
I just start ignoring everything that is not the things being linked. What is the author trying to link? And what is the gap in that link?
I start with the conclusion. Photographs are interpretations. Ok... where do we talk about interpretations? We don't. We do talk about expressing worldviews with photographs.. Ok the author is trying to convince us that expressing a worldview and interpreting are the same thing.
Start with what is in the conclusion, try to find the evidence of the conclusion, and identify the missing link that would make the evidence actually prove the conclusion.
@mostxareyallyarezthusmostxarez Yeah can be false is not false, just an ability to be so. "Can be P and B" is not a negation. I think "One is a pilot and is blind" is what was meant. That is P and B. I don't know it probably doesn't matter.
If you can be blind and be a pilot, but there are no blind pilots then "No pilots are blind" is true. No getting around that
@armiduh Yeah I often read closely until I find the answer then quickly skim all the others. Been burned too many times by selecting answer A type answers, and moving on without at least glancing at the others.
I selected A on this one, and then immediately switched to E when I skimmed through the rest. Saved me some points.
@SeanWolfe It is reasonable to assume the smallest daycare is at least the size of the largest families, in general.
Its not a MBT. Assumptions are allowed. The more reasonable the assumption, the less of an issue it is the the hypothesis or support.
You are trying to force an un-reasonable assumption when a more reasonable one is more likely.
I suck at these. I'm so quick to go "age 40-60? that has nothing to do with the argument. ELIMINATE"
When that is precisely why its the answer in a EXCEPT question. The except ones get me like 50%+ of the time...
Don't be afraid to find the right answer and not even read the others. Makes it so much easier.
B eliminates an alternative hypothesis. Its the answer. Done. Next
@TeklaCo B eliminates an alternative hypothesis. Namely that something besides heavy metals in the sewage promotes resistance to antibiotics. It strengthens the correlation between heavy metals and AB resistance.
You can spin this towards ideal experiment if you spin the whole thing to be treated as an experiment, but we weren't really presented with that were we. Just a single microbiologist's opinion on some phenomena.
I had to look it up:
