Task: Question Answering
Input (English): passage: Red Velvet cake is traditionally a red, red-brown, or ``mahogany'' colored layer cake, layered with white cream cheese icing or Ermine frosting (sometimes called ``cooked roux'' frosting). It has a distinctive fluffy texture owing to the gas-producing reaction of alkaline buttermilk with acidic vinegar and/or acidic non-alkalized cocoa. The cake is commonly served on Christmas or Valentine's Day. Common modern red velvet cake is made with red dye, however the red color was originally due to non-Dutched anthocyanin-rich cocoa.
 question: is red velvet cake chocolate cake with red food coloring?
Output (English): Yes
