Here is the original item:
Whenever Delores makes her infamous rubbery meatballs. David sneaks them
off his plate and into the willing mouth of Jellybean, the family's
terrier.
You chose to remove the period after meatballs and combine the two parts, like this:
Whenever Delores makes her infamous rubbery meatballs
David sneaks them off his plate and into the willing mouth of Jellybean,
the family's terrier.
Unfortunately, removing the period will not fix the error. Review the rules.
