Passage Three Did you know that a turtle can lay twelve eggs in one minute? A large sea turtle lays around 150 eggs at a time. She lays all these eggs in just a few minutes. Large sea turtles live in the warm seas of the world. Except for when they lay their eggs, they spend their whole lives in water. When it is time to lay their eggs, the females swim to land. They usually return to the place where they themselves were born. How they find their way back there is a mystery. When they reach shore, the big, heavy turtles crawl slowly up to the high water mark. Using their flippers, they pull themselves along the sand. They struggle like mountain climbers to attain their goal. When they finally reach dry sand, they rest before beginning the difficult task of laying eggs. The turtles lay the eggs in deep holes and cover them with warm sand. The sand protects the eggs from harm. Then the females leave them. After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake in one spot. Then you would see tidy black balls coming out of the sand. The tidy heads of baby turtles! Baby turtles have a build-in sense of direction. As soon as they are hatched, they head for the water. Once the babies swim out to sea, they don't touch shore again until it is time for them to lay their own eggs. 41. The first sentence lets us know that this passage is about ______.
A.
turtles
B.
oceans
