(3) Fire, in fact, has been a significant factor in human development and progress in many ways.

This is the main idea. The rest of the sentences support the idea that fire has helped human development and progress. It says that it has allowed humans to "travel into regions that were previously too cold" and "to sleep securely". The passage then continues to talk about how when humans learned to control fire it made significant changes in how long people were able to be productive since they no longer had to rely on the sun for light.

What does this mean?

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.
