Question

what is wrong with this sentence " often a colony of wild honeybees builds it's hive in a hollow tree"

Answer 1

The wrong word is it's. It is supposed to be its. It's means it is. :)

Answer 2

There's 3 main issues.
1. You should capitalize the first letter of the sentence.
2. it's means it is, so you should change it's to its for possession.
3. Add a . at the end of your sentence.

Hope this helped!
