Good job — your sentence is correct!
Original: You can enter a platypus's burrow from the land or from the water.
Why it is correct (easy steps):strong
- Who: "You" is the person who can do something.
- What: "can enter" is the action — it tells what you can do.
- Where: "a platypus's burrow" is the place. The apostrophe + s ("'s") shows the burrow belongs to the platypus.
- From where: "from the land" and "from the water" tell the two places you can use to go into the burrow.
Two simpler ways to say the same thing:
- You can enter a platypus's burrow from land or water.
- A platypus's burrow has entrances on land and in the water.
One small note: Writing platypus's is fine and clear for showing ownership. Everything else (word order, punctuation, and meaning) is good. Keep writing great sentences!
