#7 - Those who particpate in local politics include

[Cmoeckel]

Didn't have any difficulty on this question, but just wanted to clear something up in my head regarding these types of questions:

Is an implicit assumption in every of one of these formal logic questions that we are operating in a system with >0 participants. I.E. the correct answer choice would not follow if we assume 0 participants in local politics. Kinda silly on this question, I know, but I've made this assumption b4 on more complicated questions so just wanted to confirm.

Thanks guys, you rock

We do! And the short answer is yes. While you're always prefacing an answer in your mind where possible prior to looking at the answer choices, you also want to be able to "mold" your understanding of the implicit conditions within the stimulus to match a particular answer choice. And of course, in general, we're assuming that conditions in the stimulus, where set out, are applying to non-zero probability events.
