I chose "D," or Four minimum. Here was my reasoning: <br /><br />She votes for the gun control bill only if she votes against the environment bill. <br />[G --> ~E] <br />Unless she votes against the judicial activism bill, she will vote for the immigration bill. <br />[J --> I] <br />She will vote for either the environment bill, the judicial activism bill, or both. <br />[E or J] <br />She votes for the gun control bill if she votes for both the health care bill and the defense bill. <br />[(H&D) --> G] <br /><br />Valid inferences from the rules: <br />E or I <br />(H&D) --> ~E <br />(H&D) --> (I&J) <br /><br />I mainly ran the modus tollens a bunch. From ~I it follows that ~J; from ~J it follows that E; from E it follows that ~G; from ~G it follows that either ~H or ~D. <br /><br />So the minimum is 4: ~I + ~J + ~G +~H/D. That's four. It's only 3 if the question meant to as say something like "minimum in addition to I." If so, then it's 3, not 4. But it didn't say that. Where did I go wrong?

Thus voting against the judicial bill (NOT J) is a necessary condition for her deviating from her norm (which was 'voting for') and instead voting against the immigration bill (NOT I)Anonymoushttps://www.blogger.com/profile/14350405105802934749noreply@blogger.comtag:blogger.com,1999:blog-10294095.post-43033163281459342122013-11-24T21:28:22.236-05:002013-11-24T21:28:22.236-05:00Steve Swartz can you please explain the answer to ...Steve Swartz can you please explain the answer to #1?<br />Anonymoushttps://www.blogger.com/profile/10307642847309532926noreply@blogger.comtag:blogger.com,1999:blog-10294095.post-2801605189338869732013-09-02T07:51:29.117-04:002013-09-02T07:51:29.117-04:00How can "only if" introduce a necessary ...How can "only if" introduce a necessary condition and "if" introduce a sufficient condition?

I"m confused about how it turns into J--I?<br /><br />From my understanding of Steve's tips, you would turn Unless into If not. So is my thinking correct if I then consider the rule as, "If not voting against judicial activism, she will vote for the immigration bill." By turning the sufficient statement into a double negative, it becomes a positive?
