If a potato is blue, what disease does it have?

There are blue potatoes, but they don't have a disease. Hope this helped ☻

There is such thing as a blue potato. IT DOESNT HAVE A DISEASE!!!

Betray, destroy, and obey do not need to be changed to add the suffix -ed, because the "y" at the end of each word is preceded by a vowel  (so  they would be spelled  "betrayed," "destroyed," and "obeyed").

but hurry is different; it has to  be spelled "hurried" because the "y" at the end of "hurry" is preceded by a consonant.
