The original passage is mostly clear, but it can be slightly improved for better clarity and correctness.
Original passage:
"The polar shores are covered in ice and snow. Animals come together to grow and keep their young safe. Polar bears hunt in the water, and albatrosses take to the skies."
Corrections and explanation:
- In the second sentence, "Animals come together to grow and keep their young safe." - The word "grow" is a bit vague here. Animals usually "grow up" or "raise" their young. It is better to say: "Animals come together to grow and to keep their young safe" or even better, "Animals come together to raise and keep their young safe."
- Also, since they are keeping their young safe, "to raise" is more common when talking about animals caring for their babies.
- Otherwise, the punctuation and grammar are correct.
Improved version:
"The polar shores are covered in ice and snow. Animals come together to raise and keep their young safe. Polar bears hunt in the water, and albatrosses take to the skies."
