If you have taken some quotes off a website,reduce them.Put in more of your own wording rather than copy and paste.
If it is your own original work ,it will keep your score lower,however if it is copied ,it is not good and best re-done.
Maybe you took it from your own website-if so you could just leave it,but you are better off to publish on hubs first and then send it to website with backlinks to hubs.
Just tweak it a bit if you can't find a reason,there may be similar
stuff already published,so changing the odd word here and there may help.
You have nothing to worry about ,so long as it's not plagariased
