Here is the passage again:
Scooting the glass of iced tea closer to her plate. Brave Vanessa dipped
the tortilla chip into Pedro's infamous hot sauce.
You chose to use Punctuation Rule 4 to fix the problem:
Participle phrase + , + main clause.
The correction looks like this:
Scooting the glass of iced tea closer to her plate,
brave Vanessa dipped the tortilla chip into Pedro's infamous hot
sauce.
Well done! You deserve that cyber pizza!
