#help why can't the conclusion in number 8 be written as e → UGR → NMI ? does eUGR mean something different from e → UGR?

#help could the 'wish-amend' sufficient condition just be kicked into the domain? seems to make the lawgic more complicated than it needs to be by not doing that?

#feedback why is the lawgic translation not a part of the answer to #9?

#feedback please point me to the lesson where the concept of a 'stimulus' is thoroughly explained. i can't find it anywhere?

#help

the example:

(1) Jon must (either) enroll in Economics 101 or Political Science 101 this semester.

Doesn't the 'either' make it the same as the (2) 'either/or' meaning? This is example is supposed to be in for inclusive 'or'? Can 'either' be included for both the (1) and (2) meanings of 'or'?

#feedback when does he explain exactly what a stimulus is ? cannot find that anywhere

#feedback do we ever get a plain explanation of what a stimulus is ? where can i find that?

#feedback 20.1 the answer here is really confusing. essentially, this is saying the same thing as the previous negative comparatives right?

there is no statistical evidence that humans act selfishly more often than the act unselfishly, meaning that 'A doesn't win', meaning that humans either act selfishly less often or equally often as they act unselfishly. the answer here sort of says that, but is worded completely differently from the above questions that give answers to negative comparisons. unless i am understanding this wrong? #help (Added by admin)

#help in 2.2, is 'influenced by cultural and economic factors' a modifier of design?

above it says 'vote' is a modifier, but i think it means 'to sabotage the vote'? how can 'vote' itself be a modifier here . . . i believe in this case it's the predicate object? #feedback #help

#feedback when lawgic isn't used in the answers can we explicitly be given the reasoning as for why not? not super clear why some answers are so thorough while others go almost entirely unexplained.
