Diels-Alder Reaction Stereochemistry

Predict the product(s) and stereochemistry for the Diels-Alder reaction between (E)-1-phenyl-1,3-butadiene and maleic anhydride. (a) Draw the endo and exo products. (b) Which product is kinetically favored and why? (c) Which product is thermodynamically favored? (d) How would the reaction rate change if the diene had an electron-withdrawing group instead of a phenyl group?
