Negating an (And/Or in Conditionals) relationship

Hi dear 7sagers, and sages,

First of all, I am having trouble understanding the difference between negation and contrapositive but I think I am slowly getting it.

What troubles me, however, is how to negate a relationship, or in other words deny it, which has an And/Or statement in the conditionals. So, for example, I will use @JY's example from his lesson on DeMorgan's Law:

"If Tom plays, then Jerome and Simmi play too"

Translated into lawgic that would be: T→(J and S) (which could be split)

Now, if we negate the statement altogether, what happens then? "It could be the case that if Tom plays, neither Jerome nor Simmi play" am I right? ....T→NOT(J and S)

Moreover, how do you translate that? T→/J and T→/S ??? Or in other words, T→(/J and /S) (which could also be split)

does anyone think that the projected -11 curve (from powerscore) for this LSAT is too low? I also wrote the NOV lsat and this one felt without question harder.

If you have U+, then PT's 81 is in your syllabus. You can also purchase it as an add-on too.

I am only bummed about the non-U+ members who purchased the test and don't get the live commentary. Or maybe I just don't know how to access it... I am only able to get video explanations for the LGs. Regardless, thank you for this super nice gift for the September takers!

There are no video explanations (and the Live Commentary) for LR and RC for PT81 yet. I think J.Y. will post them after these BR sessions.

Losing focus after the break

It has occurred to me that every time I take the 15 minute break after the third section and come back to start section 4, I lose focus and I can't get back into the questions until about 15 questions in... I am not very attentive and overlook some of the details in the Question Stems... Has anyone experienced this as well and does anyone have any advice?

If BUT only if

This has been asked before but for the sake of it I am asking it again. Is the statement "V happens if and only if Y happens" represented as Y(----)V (/V(----)/Y). Thank you for the clarification

Well that was a little helpful but I was looking for more... In my opinion, C is a necessary assumption AC: if it is the case that in most cases where planets have been found orbiting a distant star, it is not the case that there are more than one planet... Yeah, if that's true, then there is no way that one planet would have been thrown off by another planet. But I don't see how it would strengthen it... Maybe it would because there are at least two planets, therefore making it possible for one planet to change the other's trajectory...

Now B, i like better... If there was an indication that at least one of the planets in out system was affected by another planet, AND SINCE ALL the planets in our system are in circular orbits, then that wrecks the possibility that a planet could be put into an oval trajectory.... Hence weakening the hypothesis that another planet threw off that other planet in that other system....

Or am I completely misusing the necessary assumption negation method for Strengthening questions?

Let me give my reasoning as to why I think A is the wrong AC... I did the same PT as the one where @ took the question from just the other day and I think I might be able to solve our problems here.... In the original question, the species compared are each from the same family...

In other words, like @'s example, we have one type of fish and another type of fish, electric and non-electric... Obviously the shark won't eat the electric ones cause it would get electrocuted, so it focuses on non-electric... (well mind you that's my assumption but the effect is the same... they don't eat electric fish)

Context: sharks do not eat electric fish

Observation: this one type of non-electric fish lights in flashes to confuse the shark even though it uses much energy

Hypothesis: the non-electric fish evolved this feature as a means of avoiding sharks/predators

A) no electric fish lights up like our type of non-electric fish

.... don't you see how this would weaken it? If none of the electric fish light up like it then the potential presumption that the non-electric fish lights up like them in hopes of appearing as electric is destroyed...

I still can't figure out how the others strengthen it, but I have managed to see why A doesn't... -_-

With regards to @'s alternative question, I think the confusion comes from the fact that we are comparing humans to cats... And the assumption that the predator eats the other species is missing too, which is sort of changing the overall argument from the original Question.

A parallel to your parallel:

The Crayon Pony Fish lights up in an abrupt series of flashes and colors. While leopard sharks don't eat electric jellyfish, non electric fish like the crayon pony fish need to confuse the leopard shark to escape. Scientists therefore speculate that the crayon pony fish's lights, which burn an extraordinary amount of calories, evolved as a means of confusing the leopard shark.

(A) No electric jellyfish lights up like the crayon pony fish

(B) Getting eaten by leopard sharks is not how most fish die

(C) Many other fish have lights similar to the crayon pony fish

(D) It burns far fewer calories for fish to light up than for aquatic mammals

(E) The leopard shark preys on many non-electric fish.

A) is not the right answer choice, in fact, it would weaken it...

B) I think B has the highest support although to me it's quite hidden. I do have to agree with @'s argument for B... and that goes for @'s stimulus as well.... it seems very plausible...

C,

D, and

E are all hard to defend...

What about negating a "most" statement?

E.g.

"Most of the island's permanent residents oppose the passage of the law"

Would the negation be

"It could be the case that none oppose the law" (Which would also include the possibility that all support the passage of the law") My reasoning here comes from the fact that MOST is in fact a SOME statement, because some includes everything from 1 to 100.

I am very confused. What if there was some other source of sulfur dioxide in the atmosphere that caused the levels to increase and all of the regulations were actually followed? Answer choice B assumes so much, and its logic runs contrary to what we are taught: "Never assume stuff". Furthermore, answer choice "D" is a much better choice because the assumption we are asked to make is much weaker than that in answer choice "B": the STIM says that there were regulations imposed on coal plants in order to reduce the pollution... AC D says that coal plants are one of the main sources of pollution... HECK YEAH... if the government had to introduce regulations on them, then that most likely means that they are heavy pollutants... It's so obvious,,...

Average vs. Highest Score for Canada and US

I apologize if this question has been asked before but I was unable to find any previous discussions. Would anyone be able to point me to a source where I can find information about which schools average your LSAT scores and which ones only take your highest score? And that goes for both American and Canadian law schools. I would very much appreciate any information because I am currently on the precipice of a mental breakdown about whether I should postpone the test to September and cancel my registration next week! Thank you :)

Reading Comprehension Strategy

Ok, we've talked a lot about Logic Games strategies as well as Logical Reasoning strategies, primarily about skipping, but I feel like I haven't yet found or come up with a solid Reading Comprehension skipping strategy. Yes, I have been able to come up with a personal amalgamation of JY's memory method and other methods but I am yet to figure out how to skip questions. First of all, do you guys ever skip questions on one passage, only to return to that passage after you've read some of the later passages? I think that's a bad option and I very rarely do so. Second, do you rather skip questions within a single passage with the intention that some of the following questions will bring about an explanation or light a bulb in your head about what that one previous question you skipped was asking? And finally, I have generally tried to stick to the rule that I have to be done the first passage within the first 8-9 minutes, and the second passage no later than 15-16. Do you guys agree? Any advice, comments are welcome :)

Difference between Weakening and Flaw Answer Choices

Hi Guys,

I just have a question for weakening / flaw answer choices. Although there is some over lap between the two, I know that they are distinct and I understand how to approach them differently. However, sometimes I have difficulty distinguishing the KEY difference between their answer choices. For example, if a answer choice in a weakening questions presents a flaw can that be the right answer choice? In other words, what are they key differences in their respected answer choices.

Thanks,

Nas

Ideas for a snack during the break

Hi everyone, I was hoping to start a discussion where we can post ideas about possible snacks during the 15 minute break. I myself tried with raw almonds and dried prunes on my first actual LSAT try... I was feeling great, mentally and physically, no hunger, not full either, but my score was low. Of course, this is just a simple correlation (maybe there was no relationship and a third factor, not being prepared enough, which influenced my score) but nonetheless I would like to know what are some good options people have tried in the past. Thank you very much and I look forward to this discussion :)
