Double spaced
In MLA format you always used a double spaced format for your essays or reports.
Yes I believe so. The way that I interpreted my teacher saying something kind of similar that you just write down anything you come up with a certain topic.
I'm not sure but I think this is what it means:
When [we] ran in, [we] saw the squadron waiting. This means they ran in wherever they were running in and saw a group of military soldiers that were lined up in a military formation, called a squadron. They saw their friends waiting for them, troubled, looking out at the sea. They beached, or laid the ship (her) ashore and grounded her/the ship to shallow water in the sand. Then they got of the ship and waded through the water onto the sandy beach.
I hope I helped! Again I'm not sure if I am correct but I hope I helped you somewhat.
