Question #1570

Does this shortcut work for all quantifier questions?

Hello, I diagrammed as follows: PCM some SFI PCM --> not LS PCM some WS Because you cannot combine two "some" statements, I looked only at answers that had "not LS" in them (or contrapositive LS), because that would have to be used to deduct these statements. Is that a valid and accurate way to go through quantifier questions on the exam? Or is there potential on a more complicated quantifier question that this could lead me to an incorrect answer choice?

    @alicat6, great question. This is a great strategy. Just keep in mind that quantifier statements (including "some," "many," and "most") can link up with conditional statements if the two statements in question share a term that is the sufficient condition of the conditional statement (and on the right side of the quantifer statement. Here's an example: Some Californians live in LA. If you live in LA, you like warm weather. CA<-some->LA LA-->like warm weather We can combine these statements to conclude that some Californians like warm weather. Keep up the great work, and let us know if you have any other questions!
