2. One January morning, two neighbors, Olson and Peterson, awaken to find a large snowdrift' covering the driveway that both of them use. A snowplow will not arrive until late afternoon. Shoveling snow is hard work and neither likes to do it. But if the driveway is not cleared, neither will be able to go to work and this is costly for each of them. Each neighbor can either attack the snowdrift with a snow shovel, or stay in the house and drink coffee. If both shovel the snowdrift, they each get a payoff of -2. If only one of them shovels the snowdrift, the neighbor who shovels has a a payoff of -5 and the neighbor who stays in the house gets a payoff of +1. If neither shovels the snowdrift, they both have to stay home until the snowplow comes and each gets a payoff of X. 'For the information of southern Californians: A snowdrift is a thick white layer of atmospheric water vapor frozen into ice crystals, swept by the wind into a deep pile. 2 A) Show this game in strategic form. B) For what values of X is there only one Nash equilibrium? What are the strategy profiles in this equilibrium
