Our body's circadian clock system is affected by many factors, one of which is light. Studies have shown that light can effectively deceive the brain into "day mode", even if the eyes of the person were closed at the time. Light therapy to help us adjust jet lag, including continuous light and flashes at different intervals, and flashes that last only 2 milliseconds every 10 seconds are most effective.

Which of the following, if true, best supports this view? ["The darkness between each flash helps to restart the eyes, thus restoring the eyes' sensitivity to light.", 'Most people who experience "flash processing" during sleep are not affected by the flash.', 'Go to the city two hours early in the time zone, and people who have received light therapy two hours before sunrise on the departure day will not feel jet lag.', 'It takes a long time to adjust the time difference by yourself, and the average time difference can only pass one hour every day.']
