Draw the intermediate in this stepwise reaction sequence that uses proton transfer reactions to convert the starting material to the product. Since this intermediate is resonance stabilized, draw any one of its resonance structures for credit. Do not include lone pair electrons in your answer. $($Hint: As a first step, use ${?}^{-}OH$ to remove a proton from the $C{H}_2$ group between the $C=O$ and $C=C.)$
