In this question the conjunction is represented by " & "; disjunction by " v "; the conditional ("if...then...") by the arrow, " " ; and the bi-conditional by the double arrow, " ". And negation is represented by the tilde " ~ ". How does Q follow as a conclusion from these conjoined premises? There are three premises above the dotted line, and they are written as a single line with "&" holding (conjoining) them together. (P v Q) & (P R) & (~ R) ------------------------------------- Q ...and the reasoning sequence that explains how Q follows is... Group of answer choices 1. (P is true v Q is true) is one of the premises 2. by subtracting P 1. together (P R) & (~ R) imply ~ P (by modus tollens); 2. since (P v Q) is one of the premises, and since P is false (~ P), then it must be that Q is true. 1. we can add Q to ~ R and that becomes "R is false and Q is true"; 2. and that implies Q is true
