Please explain

@kidarby we would diagram the first sentence as follows: "If Suarez is not the most qualified of the candidates for sheriff, then Anderson is." not SMQC ==> AMQC not AMQC ==> SMQC "Thus, if the most qualified candidate is elected and Suarez is not elected, then Anderson will be." PR: MQC ==> E not E ==> not MQC P: S = not E not E ==> not SMQC So not SMQC ==> AMQC C: AMQC ==> E (B) exhibits this exact patter of reasoning: "If the lowest bidder on sanitation contract is not Dillon, then it is Ramsey." not DLBSC ==> RLBSC not RLBSC ==> DLBSC "So if the contract goes to the lowest bidder and it does not go to Dillon, then it will go to Ramsey." PR: LB ==> C not C ==> not LB P: D = not C not C ==> not DLBSC So not DLBSC ==> RLBSC C: RLBSC ==> C Notice that you are given either/or options for most qualified (stimulus) and lowest bidder (B). We are then told that if this criterion (i.e. most qualified/lowest bidder) is elected (stimulus) or awarded the contract (B) and it is not one of our two options (i.e. Suarez/Dillon), then it must be the other (i.e. Anderson/Ramsey). Hope this helps! Please let us know if you have any other questions.
