Sufficient and Necessary - Example 5

Why on example 5 do we diagram out ways to apply this general principle/how do we know that? On other examples it has given us something that we have apply - how on this one do we know to diagram out ways to apply?

@hales,

Happy to help. We can tell what we need to do based on the question stem.

For this question, the stimulus gives us the condition that

Democracy function well - >electorate is moral and intelligent

electorate is not both moral and intelligent - >democracy won't
function well (contrapositive)

We're looking to infer something based on this statement.

Answer (C) gives us the contrapositive of the stimulus, as it says

electorate not moral and intelligent - >democracy will not function well

Thus, it's something that can be inferred and is the correct answer choice.

Does this answer your question? Let us know if you'd like more clarification!

Yes but is the contrapositive not "electorate is not both moral OR intelligent" rather than 'and'?

Great question.

The statement is

electorate is moral and intelligent.

The contrapositive is that the electorate is not both moral and
intelligent. This means the same thing as saying that the electorate
is not moral OR the electorate is not intelligent.

These statements mean something different from what you wrote. Saying
that the electorate is "not both moral OR intelligent" doesn't make
sense because the statement is already saying that the electorate
isn't both of these things. The OR, therefore, doesn't make sense
there.

The problem appears to be where you're placing your "or" and how you
did not see how saying that the electorate is not both moral and
intelligent means the same thing as saying that the electorate is not
moral OR the electorate is not intelligent.

Does this make sense? Let us know if you have any other questions!
