can someone explain E? i get "it doesn't matter" but i kind of saw it as close to the suspicious that the rat colony may not be similar to another rat colony. if AC E said "Have other species of rodents rat colonies been used in experiments of the same kind?" would it be more of a correct answer?

could someone clarify why C is right? i was reading "prints of all latter works are available in the museum store" but it didn't say the prints of the former work weren't. it just clarified that the all of the latter work was in the museum. so then i was trying to hunt for an answer choice that may have said that the former aka loan from private collection = hopper's nighthawks or say something about "if the nighthawks are not part of the loan, then there must be another section of the store that sells neither of the categories"?

i'm having a hard time going from growth of plankton to decaying of plankton. i saw it as a contrapositive, so i was trying to map it out oppositely. any help?

I got discouraged from A because the stim said "indicate in some other way" but the "clearly" threw me off as too strong. is there a way to resolve this?

Also, does legally entitled mean that it's a requirement or that i have the right?

@Gotham i had this same exact thought and issue but i can't seem to get to bravery > gryffindor from the vid?

@A man has no name i also was struggling with this. i think that the contrapositive allows for us to see the argument in a different angle that is still valid. negation puts the argument at risk and makes it invalid?

contrapositive = argument in different light + valid argument

negation = finding a loophole + invalid argument

for example -

all dogs are pets. [D > P]

contrapositive: no pets are not dogs. [/P > /D]

negating it:

it is not the case that all dogs are pets. [D <s> /P]

it is not the case that no pets are not dogs. [/P <s> D]

i could be totally wrong but this is how i kinda see it

@StephanieTorres from my understanding, negating is for the entire conditional (negating the relationship). contrapositive is just another way to look at the problem i think?

@Courtney Pierce thank you, i thought i was crazy. not trying to find an easy way out but also trying to find a loophole

Q4: Some graduate level philosophy courses are available to undergraduates.

the answer said: No graduate level philosophy courses are available to undergraduates. (G → /U)

but doesn't (G > /U) translate to "all grad level phil courses are not avail to undergrads"? shouldn't the answer choice should've been then (/G > U) instead? not saying the answer is wrong but i think the translation part was the contrapositive?

Q5: i'm having a road block. is it possible to translate this q to english?

/F <s> RSW

/F and RSW

@EmPerezPD

if you meant: "/kittens -m-> children home", then i don't think it's correct. a few lessons back show that there's no contrapositive for most (assuming that's what you're doing).

this may be a dumb question, but does anyone know if the first one in these comparisons normally the winner? if not, which case would there be a winner for the second?
