Good job noticing this sentence! Let’s make it clear and correct in a few small steps.
- Find the problem: The sentence says "A lonely piranha" (that is one piranha) but later uses "they" (which means more than one). The words should match: singular with singular, plural with plural.
- Fix it: Here are easy corrected versions:
- Piranhas alone aren’t scary, but together they are quite dangerous.
- A single piranha isn’t scary, but piranhas together are quite dangerous.
- A lonely piranha isn’t scary, but a group of piranhas is quite dangerous.
All three mean the same thing. Pick the one you like best. Also remember to put a period at the end.
Try this: Change the word "piranha" to "shark" in the sentence and make it correct.
