Two reasons that the most of the sunlight received in the polar regions is reflected back into space?

Most of the sunlight received in the polar regions is reflected back into space primarily due to the high albedo of ice and snow, which reflects a significant portion of incoming solar radiation. Additionally, the low angle of the sun's rays during much of the year reduces their intensity, leading to less absorption of sunlight. These factors combined result in minimal heating and significant reflection in these regions.
