    I'd like to know about " The only". Is this a NA indicator, even if THE is in front of it? We have no info about it. Thanks. The only answer I need is about this question.

    I believe that "The only" is group 1, it indicates the sufficient condition.

    Monday, Sep 30, 2024

    Yes! Thank you. I researched this over the last 2 months! It’s actually “ the only- only “ that is sufficient!! All the other “ only”’s are necessary indicators 😊

    #feedback What is the point of the timing posted next to the articles? Should I really only be taking 1-3 minutes to read and absorb these complicated topics? I find that I want to complete a full section when I study and have drawn up a schedule based on the syllabus. But, at least through the early portion of the course, this is very dense information, and the study times are misleading.

    This is super reassuring as I am setting up my study schedule to do 2 hours a day on top of being a full time high school science teacher -- I feel like I am getting through these so slowly & it is discouraging. How is the 1 hour a day method working? Does it get better? SOS

    Wednesday, Oct 25, 2023

    Yeah exactly. Also, the drills take me 1-2 hrs. a piece even though they require "30 minutes." That's with writing some of them down.

    Wednesday, Dec 6, 2023

    Theres no way that anyone can go through these in like 1-2 minutes or even thirty minutes . I legit wrote down flashcards and will now be memorizing which could take me like an hour or more. The 1-2 minute thing is super misleading and if you're doing everything that quickly , it for sure is not the right way to study. I take hours on the drills because I understand the drilling part is super important to really understand the content and understand the grammar. This section has been taking me especially slow.

    Monday, Jan 8, 2024

    I think as you get better at recognizing these drills/patterns you wont be needing to spend quite as much time. Some lessons I immediately grasp and my brain is always able to make a differentiation, you should be studying to be able to rapidly recognize patterns as opposed to trying to memorize them.

    I made flash cards to help memorize group 1-4 conditional indicators, thought I’d share in case it would be helpful to anyone else. I’m redoing this course after getting through most of it and taking the lsat and not doing as well as I hoped. Looking back I realize how important it is to know these. https://quizlet.com/1153975729/lsat-7sage-conditional-indicators-to-share-flash-cards/?i=71yhg9&x=1jqY

    Hi there! It's the morning of my first LSAT and I came back to this lesson to review the 4 groups before heading off to my test. I saw your comment and thought I'd contribute my two cents: you don't need to necessarily memorize these indicators right now. As you move into LR and continue practicing conditional logic, you'll notice these indicators kind of become second nature to you. Some of them will stick immediately and they'll mostly be intuitive for you. You may struggle to remember others (hence why I'm reviewing this right now, "no" always makes me second-guess myself). The LSAT uses some of these indicators far more frequently than others (I'd say if, when, every, all, only, must, always, unless, and no are the most common). Refer back to this once in a while throughout LR and apply what you know, but don't stress about memorizing them fully right now. You'll understand them better once you see them in action :)

    i think i need much more fleshed out definitions of what a sufficient relationship and a necessary relationship are with some examples. Can't seem to wrap my head around the concepts and fully grasp them within the real world.

    @MPFerrari Hey, I might be a little late but something that I think helps me out a lot is "if x then y" x is sufficient and y is necessary. X is enough to satisfy Y but Y is required to make X true. Does this make sense?

    Ex: If I am in Chicago, I am in Illinois.

    Chicago is the sufficient here. It guarantees that I'm in Illinois (my Y) because Chicago is a city within Illinois.

    Illinois cannot be the sufficient in this case. Just because I am in Illinois doesn't guarantee that I am in Chicago. Chicago only makes up lets say <1% of Illinois total ground. I could theoretically be in Champaign. (At the University of Illinois)

    Does this make sense?

    Here is another example that could help:

    If I drink redbull then I will grow wings.

    Sufficient: drinking redbull

    Why? Drinking redbull is sufficient to make you grow wings.

    But I cannot say growing wings is sufficient or enough to be drinking redbull.

    Why? Because what if I somehow mutated. Died and became an angel? There are endless possibilities that are not listed.

    Sufficient: enough to guarantee.

    Necessary: must be true for outcome to be possible

    15
  • Sunday, Jul 27, 2025

    I think it means it is sufficient to make the conclusion true...

    like if I am in Austin, then I am in Texas.

    Austin is sufficient to guarantee that I'm in Texas.

    but Texas does not guarantee I'm in Austin.

    but if I am in Austin then it is also necessarily true that I am also in Texas.

    Im so lost what is the difference between group 3 and 4 if it doesn't matter which side you choose. technically you are doing the exact same thing just you decide which is going to be sufficient or necessary based on which idea you choose?

    Tuesday, Apr 7

    @lsatdiva12345 Remember that the rules aren't any fundamental information about the logic, they're just shortcuts that help you jot down a lawgic implication correctly when you see one of the logical indicator words. The point of the rules is that in group 3 the sufficient condition is negated, and in group 4 the necessary condition is negated. Maybe it would be a good illustration if you built your own implications in the group-3 and group-4 patterns (/A -> B, and A -> /B), and then translated them into English. You will likely find that the words you need to use for the group 3 pattern are words like or, unless, until, without, and that you'll need no, none, not both, cannot for group 4.

    2
    Tuesday, Apr 7

    @lsatdiva12345 Said differently, the logical notions built into the group 3 and group 4 rules are descriptions of how English uses these sets of logical indicator words (at least in the context of LSAT questions).

    1
    Wednesday, Jul 15

    @lsatdiva12345 i had to stop thinking about is as the 'choose whichever one' advice and instead make the rules:

    'unless, without, or, until' = treat as introducing a necessary condition with a negated sufficient condition (/A --> B)

    'no, none, not both, cannot' = treat as introducing a sufficient condition with a negated necessary condition (A --> /B)

    Whats the concept behind "never"? Its not listed on the diagram as an indicator but was used in an example

    Edited Tuesday, Mar 17

    @Kerington43 never is a group 4 negate, necessary indicator that functions the same as cannot.

    I'm confused on how "the only" in group 1 differs from "only" in group 2. Does anyone have an example of how this works?

    "The only people who got an A studied."

    Does this mean everyone who studied got an A? No -- just that everyone who got an A studied. But, there could have been many people who studied who did not get an A. So here, "the only" introduces the "if" part of the conditional:

    Got an A --> Studied

    "Only people who studied got an A."

    This expresses the same relationship above. It's not saying everyone who studied got an A. It's saying studying was necessary for an A. Only people with that quality got an A. Here, "only" introduces what's necessary.

    "Got an A --> studied"

    Tuesday, Jan 27

    @Kevin_Lin Can't you just remove the "the" or add a "the" in each of your examples and get the same meaning? Still not seeing how adding "the" before "only" changes the entire meaning of the sentence compared to just "only"

    @epayne17 "The only people who make over $50 million a year are pro athletes."

    What's sufficient and necessary in that example? Is that saying everyone who makes over $50 mill a year is a pro athlete? Or that every pro athlete makes over $50 mill a year?

    "Only people who are tall are good at basketball."

    What's that saying? That everyone who is tall is good at basketball, or that everyone who is good at basketball is tall?

    1
    Thursday, Jan 29

    @Kevin_Lin Right, so removing "the", resulting in "Only people who make over $50M a year are pro athletes" has the exact same meaning than when you have "the" at the front....
