Corrected sentences
A falcon’s beak is short, strong, and hooked — perfect for catching and tearing.
A prairie dog’s burrow is like an underground city. It has several entrances, vents, a bedroom, and a toilet.
Why these changes?
- We added a comma after "strong" because when you list two or more words (short, strong, and hooked), a comma helps make the list clear.
- The long dash (—) before "perfect" shows extra information about the beak in a friendly, strong way.
- We added a comma before "and toilet" (the Oxford comma). It makes the three items in the list (entrances, vents, a bedroom, and a toilet) clearer, especially for young readers.
- "Vents" means little holes or openings that let air in and out, so the burrow can breathe.
