Correct sentence (simple):
Hares have shorter front legs, so it is easier for them to run uphill than downhill.
Or (singular):
A hare's front legs are shorter, so it is easier for it to run uphill than downhill.
Why we changed it — explained for a 6-year-old:
- Make it easy to say: Instead of "Hares' front legs," we say "Hares have shorter front legs." That way we don’t need the apostrophe and it is simpler to understand.
- Add the missing word "to": The original missed the word "to" in "for them to run." We need "to" so the sentence sounds right: "for them to run."
- Show the reason clearly: We use "so" to show cause and result: the legs are shorter, so running uphill is easier.
- Singular vs plural: If you talk about one hare, use "A hare's... it." If you talk about many hares, use "Hares... them."
Short practice:
- Wrong: "Cats tail is long and makes it fast."
- Better: "A cat's tail is long, so it helps it run fast."
Great job noticing that sentence — you fixed it!
