No stupid questions

Have you ever heard that? No stupid questions just unasked ones? Well here is one for you all and maybe someone can help me! As I posted before I'm entering Amazon's Breakthrough contest. As part of their requirements, I need to have a from 3 to 5,000 word excerpt. Okay I have that! Now I don't claim to be very computer savvy but this one stumped me. The excerpt needs to be double-spaced but no 'hard' ones using return. I found the margins and changed those. I changed the font and font size, check. So how do I change the sentence spacing?

I'm using a cheap version of MS works, but I do have Open Office. Tried that too, but couldn't make heads or tails of it either. So will someone take mercy on this poor writer? :)
