Correct sentence:
Animals stash food in burrows, in trees, or in the ground.
Why this is correct (simple steps):
- "Animals stash" is correct because we have more than one animal (animals) and the verb "stash" matches them.
- We are listing three places, so we separate the items with commas and use "or" before the last item: burrows, in trees, or in the ground.
- Putting "in" before each place ("in burrows, in trees, or in the ground") keeps the sentence even and easy to understand. You can also say "in burrows, trees, or the ground."
Easy alternatives:
- Animals hide food in burrows, trees, or the ground.
- Some animals store food underground, in burrows, or in trees.
- Or simpler: "Some animals hide food in burrows. Some hide it in trees. Some hide it in the ground."
Nice sentence — just add the comma and the word "or" and it sounds great!
