Hello,
For this question:
Based on the study results, how is the relationship between inadequate sleep and hunger best described?

There is a direct cause and effect relationship between sleep and increased feelings of hunger.
There is a positive correlation between hunger and inadequate sleep.
There is evidence that inadequate sleep causes hunger.
There is a negative correlation between hunger and inadequate sleep.

I'm confused as to how you could concluded option C is the correct answer over option B. I chose option B because I thought option C was too extreme of an conclusion to make since its a causation.

Is option C correct since this was an experimental study design and therefore you can concluded causations between variables vs an observational study would only produce correlations?

Thanks

Hi,
Can I send you a picture of the passage to your email? I think that's the easiest way to send it since I can't figure out how to post pictures on the forum.

Thanks
