I wonder why my answer is till incorrect. Please help!!

In the presence of sodium ethoxide and ethanol, (R)–3-chloro-2-methylhexane can undergo an elimination reaction as well as the SN2 reaction. Complete the reaction mechanism for the major product of the reaction and draw that product of the elimination reaction.

Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds and including charges where needed. Indicate the mechanism by drawing the electron-flow arrows on the molecules. Arrows should start on an atom or a bond and should end on an atom, bond, or where a new bond should be created.
