Miscellaneous Logical Indicators

in Logical Reasoning 17 karma

Hey fellow 7Sagers,

I'm confused about one miscellaneous logical indicator, "is necessary".

For example, "Happiness is necessary for success".
Would the lawgical translation be S > H?

In LSAT 22 - Section 2 - Question 18, it reads,
"To classify a work of art as truly great, it is necessary that the work have both originality and far reaching influence upon the artistic community".

JY draws out in lawgic that TG > O and F.

Can someone explain to me how this is correct? I thought the lawgical translation would be O and F > TG.

    your example is correct - JY is also correct.

    A is necessary for B: B -> A
    It is necessary that A has B: A -> B

    in other words, the 2 sentences aren't built the same, you have to reword the lsat question to something like "originality and far reaching influence are necessary to classify a work of art as truly great"
