Great teaching and well thought out video. Thanks so much for putting this on UA-cam. I truly hope the LSAT starts to put in more evaluate questions now that it is a new format.
Impeccable explanation - you personalize the argument and explain the choices as if you were explaining to a child. I have felt a massive improvement as a result of your videos. Thanks so much!
Thank you so much for this wonderful lesson! Could you explain the difference between sufficient assumption and the linking idea of necessary assumption for me, please?
Sometimes they're one and the same. If an argument is making one key assumption, it could be both Sufficient and Necessary. You judge whether it's Sufficient by asking, "If this idea is true, does it prove the conclusion?" You judge whether it's Necessary by asking, "If this idea is false, does it weaken the argument?" ARGUMENT: The cake costs $30. Thus, Bob has enough cash to buy the cake. (A) Bob has $40 in cash. If true, does that prove the conclusion? YES, so it's sufficient. If false, does that weaken the argument? NO, not-having $40 doesn't hurt the argument. The argument is only claiming that he has enough cash to buy a $30 cake. If someone says, "Bob doesn't have $40", the author would be like, "So what? I never said or implied that he did have $40!"" Meanwhile an answer like (A) Bob has at least $30 in cash would be both Suff and Nec. If it were false, (if he has less than $30), then that would weaken the argument, so this is clearly a Necessary assumption. And if it were true, then it proves the conclusion, so it's sufficient. ARGUMENT: Bob plays tennis regularly. Thus, Bob must have good reflexes. (A) Some people who play tennis regularly have good reflexes. Here is an example of something that is NEC but not SUFF. If it's true, does it prove the conclusion? NO, learning that "at least one tennis player has good reflexes" doesn't prove that Bob has good reflexes. So this linking idea is not SUFFICIENT. Meanwhile, if it's false does it weaken the argument? YES, if "zero people who regularly play tennis have good reflexes", then that weakens the argument, and thus we know this linking idea is NECESSARY.
More or less for GMAT. The critical reasoning section on the GMAT is very similar to the logical reasoning section on the LSAT. Though the GMAT is not as precise with language as the LSAT. I'm not sure about the TSA, not familiar.
@@Drannn54 Yep, absolutely. They're not the same, but there are a lot of overlapping ideas. Personally, I find LR on the LSAT more challenging than CR on the GMAT.
LSAT Lab if LSAT is the toughest test when compared to GMAT, TSA actually seems too easy then. Btw, your videos are helpful for myself to know some topics better. There are not too many explanation videos about Critical Thinking
2:13 you caused an ACCIDENT in your video!!! All your answer choices are A… Did you know that Triple A, or AAA, offers 24 hour roadside assistance? They can EVALUATE your damage and get your car running again or tow it. If you EVALUATE the efficiency of AAA in comparison to its competitors, you will find AAA to be the best companion for every car owner. UA-cam is so greedy and selfish that they are probably discussing the lucrative impact of me commercializing comments and will probably create policy to prevent what I just did for AAA. Did I low key open up a pandora’s commercial box or did I create billboard signs on the tunnel walls going down the rabbit hole?
hahaha, I enjoyed that journey. fwiw, the 3 A's were intentional They're each examples of potential correct answers, so I just use the same letter so that people don't subconsciously think they're supposed to be picking "the right" one.

Glad it was helpful!
Thank so much! I was having a lot of problems with this type before watching this video! ☺️
You’re so welcome!

@@LSATLab I owe you one! Super helpful :)
The answers that you listed within each section, were those answers that are POSSIBILITIES of a correct answer?
Yes, they would be correct answers for each question type presented.
Very well explained :))
thank you
“Once every third Thanksgiving” caught me off guard. I didn’t plan to laugh while studying. Crying is another thing entirely.
are this similar explanations will work to TSA and GMAT ?

LSAT Lab but some topics like evaluating , and others are not in Gmat
