You pick a nice place you think would be nice for a dog park, then you describe how the space looks and some problems you may have for it being there.
I wouldn't use the word "discovered" it just seems a bit off. I'd rewrite the sentence with a simpler word yet easy to say and understand: "When we searched the school for damage, a new broken window was found." I hope this helps you. My apologies if this is incorrect.
I would say A but D could also be said softly
Self-Sacrifice and Love could be possible themes of the story "The giving tree". The story shows that to make people that you love happy you may need to give something up which is important to you. The Giving Tree would be a touchy-feely story full of kindness and generosity. There's definitely kindness and generosity to be found in the story, but it's pretty one-sided. Sure, in the beginning, the tree loves the boy and the boy loves the tree, but things go kind of sideways from there. The boy doesn't always treat the tree well, but never the less the tree continues to love and give to the boy in order to keep him happy.
