【C2】______people who think they are sleeping enough would probably be【C3】______with more rest.
The beginning of our sleep deficit crisis can be【C4】______to the invention of the light bulb a century ago.

To assess the【C17】______of sleep deficit, researchers have put subjects【C18】______a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We’ve found that if you’re sleep-deprived, performance【C19】______," says Dr. David. "Short-term memory is impaired,【C20】______are abilities to make decisions and to concentrate."
