The beginning of our sleep deficit crisis can be【C1】______to the invention of the light bulb a century ago. From diary entries and other personal【C2】______from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. By the 1950s and 1960s, that sleep schedule had been reduced【C3】______to between 7.5 and 8 hours, and most people had to wake to an alarm clock.
