Draw Newman projections for two different staggered conformations of butane (looking end-on at the bond between carbon-2

Question:

Draw Newman projections for two different staggered conformations of butane (looking end-on at the bond between carbon-2 and carbon-3), and predict which of the two conformations is more stable. (If you have a model kit, build a model of butane to help you visualize the Newman projections.)
