A wax is applied to the bottom surface of cross country skis to achieve a good balance between traction when the skier needs to climb a small hill and speed on downhill slopes. The coefficients of both static and kinetic friction between the waxed surface and snow increase as temperature decreases.

If the skier begins to slip backward on hills as the temperature rises during the day, they should re-wax their skis with a wax where the coefficient of static friction is larger.
To determine the appropriate type of wax for re-waxing the skis, you need to consider the change in temperature and its effect on the coefficients of friction. The question states that as temperature decreases, both the coefficients of static and kinetic friction between the waxed surface and snow increase. This means that as the temperature rises during the day, the coefficients of friction will decrease.
Since the skier is slipping backward on hills, it suggests that the problem lies with the coefficient of static friction, which is responsible for preventing the skis from slipping when the skier needs traction. To address this issue, the skier should re-wax their skis with a wax that increases the coefficient of static friction, thus providing better grip on the snow.
Therefore, the appropriate response is: One where the coefficient of static friction is larger.
