Q. about an answer on iphone app

[james.h.meyers]

I have the iphone app and was doing the P + (A) = C game.

I think I'm either diagraming this wrong or thinking about it incorrectly.

It is set up like this:

P: Those who take regular naps tend to have more inconsistent nighttime sleeping patterns than those who don't take naps.

(A): (Those who have more consistent sleeping patterns tend to sleep longer than those who don't.)

The correct answer was:

C: Those who take regular naps tend to sleep less than those who don't

I think my problem is that these are comparative statements. I started out diagraming (in my head) the premise as:

RN -> Inconsistent
[i.e. those who take regular naps implies they are more likely to have inconsistent....]

The given assumption I thought of as:

consistent (or ~Inconsistent) -> sleep longer

If I contrapose the given assumption I link the two statements as:
~sleep longer OR RN -> Inconsistent

This obviously doesn't bring me to the right conclusion. What am I doing wrong?

Thank you

Extra point for you on the LSAT! We agree that this is flawed. We're re-writing now. What do you think of this:

Premise: Those who take regular naps tend to have inconsistent sleeping patterns.
Assumption: (Those who don’t take regular naps tend to get a long night of sleep.)
Conclusion: Those who tend to not get a long night of sleep tend to have inconsistent sleep patterns.

Incorrect conclusion: Those who take regular naps tend not to get a long night of sleep.

Oh wow, I feel so proud. Yeah this looks good to me.

Yeah, it's no joke to find an error in a question that hundreds (thousands?) of others have glossed over.
