why is the negation for question four not: some large animals can move more rapidly than small animals. That feels like it follows from "it's not the case that small animals can move more rapidly than large animals".
Q5: I ended up (in english) with "Chess is sometimes not the best analogy...," which doesn't seem to comport with the written explanation but DOES seem to comport with the video explanation. (The "sometimes" allows for the possibility of a tie with other analogies.) Thoughts?
On the 4th is this statement not an all without the structural indicator? so would it not just be not all small animals can move more rapidly than large animals or does the can maybe change it so its not an all?
I understand for number 5 that just saying "chess is not the most ..." eliminates the possibility of a tie and thus is not a proper negation. However, for number 4, "small animals cannot move more rapidly than large animals" doesn't seem to eliminate the possibility of a tie in my mind in the same way. Did anyone do anything similar and does this make sense?
Doesn't "No small animal can move more rapidly than large animals can," imply "Either large animals move more rapidly than small animals OR they (referencing large and small animals) move equally rapidly." If no small animal can move more rapidly than large animals can, then it must be the case that "Either large animals move more rapidly than small animals OR they (referencing large and small animals) move equally rapidly." Am I getting off track here?
The original sentence is: "Chess is the most appropriate analogy to reporting on political campaigns."
I understand that a proper negation would be something like: "Either something else is a more appropriate analogy for reporting on political campaigns than chess is, or something else ties with chess as being the most appropriate." or "It is not the case that chess is the most appropriate analogy to reporting on political campaigns."
However, I was wondering why wouldn't a simpler negation like "Chess is not the most appropriate analogy to reporting on political campaigns" be sufficient? Is there a meaningful difference between the two, or do they functionally mean the same thing in formal logic?
For question 4, I stated that "not all small animals can move more rapidly than large animals can". This is slightly different from the answer they gave: "larger animals move more rapidly or move equally rapidly". I just want to make sure or clarify if what I said is a logically equivalent statement/answer.
wait is this lesson not like the others in that we don't really have to translate it into lawgic but just directly into English? Like for question 4 shouldn't the negation include a "some" statement because we are negating "all small animals"?
In my reversion to English, I keep forgetting to include ties. I have “no island is more tropical than any other” but exclude there could be a tie. I did the same for small and large animals and chess is the most appropriate.
To me, the negative of the animal claim is “not all small animals are faster than large animals.” I don’t see how the claim is saying that large animals are faster.
I’m also not understanding why we negate these claims if they aren’t logically equivalent to their original statement. It’s like we’re being asked to forget everything that the argument says and make our own conclusion with no evidence to back it up. It just seems irrelevant but I’m probably wrong.
so for number 4 can you say No small animals move more rapidly than large animals because to me that is the same as they move equally rapidly or large animals move more rapidly.
If small animal, then move more rapidly than large animal
negated = One can be small animal and not move more rapidly than large animal (which, don't forget, includes can move at the exact same rapid pace as large animal)
AA ‑m→ C negated /(AA ‑m→ C)
if appropriate analogy to.. then most(ly?) chess
negated = half or less of appropriate analogies for... are chess (analogies)
is this interpretation right too? I can derive meaning from it, like the original statement is that if something is an appropriate analogy to... then it's mostly chess. and then if it's negated then it's simply not that the case that (or, half or less of) appropriate analogies for....
We have been taught that negation is not the opposite. However, the answer to question 4 "large animals move more rapidly than small animals" seems to be just the opposite of the original statement. How do I see this question differently?
If I want to negate the relationship with "most," is it possible for me to use the word "few" as a negation? The reason I'm asking this is because "few" represents less than half and "most" represents more than half.
Example: Negation to question 3 would be, "Few types of pasta are made from wheat."

For Q3 can you say: half or more types of pasta are not made from wheat

Can I just slap one “It’s not the case that..” on any negation lol

on 4 and 5 cant you just slap the ol "it is not the case that..." on the front of each statement to negate it and arrive at the same meaning?
Hi! My question is about the Question #5
The original sentence is: "Chess is the most appropriate analogy to reporting on political campaigns."
I understand that a proper negation would be something like: "Either something else is a more appropriate analogy for reporting on political campaigns than chess is, or something else ties with chess as being the most appropriate." or "It is not the case that chess is the most appropriate analogy to reporting on political campaigns."
However, I was wondering why wouldn't a simpler negation like "Chess is not the most appropriate analogy to reporting on political campaigns" be sufficient? Is there a meaningful difference between the two, or do they functionally mean the same thing in formal logic?
Thank you so much for your time and help!

5/5!!!
For Q1. Is: Some people don't like Ice cream a good negation?
In my reversion to English, I keep forgetting to include ties. I have “no island is more tropical than any other” but exclude there could be a tie. I did the same for small and large animals and chess is the most appropriate.

so for number 4 can you say No small animals move more rapidly than large animals because to me that is the same as they move equally rapidly or large animals move more rapidly.
can someone explain why the negation of intersecting sects and proper notation is useful for the lsat?
For question #1, could the negation be: less than half of people like ice cream?
SA → MRTLA negated = SA and /MRTLA;
If small animal, then move more rapidly than large animal
negated = One can be small animal and not move more rapidly than large animal (which, don't forget, includes can move at the exact same rapid pace as large animal)
AA ‑m→ C negated /(AA ‑m→ C)
if appropriate analogy to.. then most(ly?) chess
negated = half or less of appropriate analogies for... are chess (analogies)
is this interpretation right too? I can derive meaning from it, like the original statement is that if something is an appropriate analogy to... then it's mostly chess. and then if it's negated then it's simply not that the case that (or, half or less of) appropriate analogies for....
these are the type of lessons that seem easiest at surface level but I keep getting the answers wrong lol
i feel like such an idiot im not getting anything right and have been revisitng lessons lol
Is it possible to use less than an less than an equal to signs?
is it right to say "less than half" instead of "ranges from none to half"?
We have been taught that negation is not the opposite. However, the answer to question 4 "large animals move more rapidly than small animals" seems to be just the opposite of the original statement. How do I see this question differently?
