Original sentence:
Across the seas, ships travel on invisible roads . They carry things to faraway lands and give travelers a safe, comfy ride.
Corrected sentence:
Across the seas, ships travel on invisible roads. They carry things to faraway lands and give travelers a safe, comfy ride.
Why this change?
- There was an extra space before the period after "roads". We remove that space so the period sits right after the word.
- Everything else looks good: sentences start with capital letters and the words make sense for a child.
- "Comfy" is a fine, friendly word for a 6-year-old. If you want a more grown-up word, use "comfortable."
Another slightly more grown-up version:
Across the seas, ships travel on invisible roads. They carry goods to faraway lands and give travelers a safe, comfortable ride.
Nice sentence — just remove that extra space and you're finished!
