Task 1 (12 points)

Read the text below and circle the letter next to the word or phrase which best completes each sentence. An example (0) has been given.

SLEEP

Why do we need sleep? __(0)__ question still perplexes scientists, but there are now several __(1)__ theories that explain our need for a daily nap. Some people need eight hours, while __(2)__ can exist on four. But the __(3)__ point is that everybody needs sleep: it is as essential as breathing and eating. Yet, __(4)__ decades of study, scientists still do not know why we do it.

__(5)__, there are some curious clues and theories. One obvious clue is that we all feel better after a good night’s sleep, and much worse if __(6)__ of a decent amount of sleep at night. In humans the need for sleep gets so strong after a few days that nothing will keep you __(7)__, with reports of people falling asleep standing up, even while __(8)__ or having intolerably loud music __(9)__ at them. Within days of having __(10)__ sleep, people report confusion, __(11)__ and hallucinations. (In case you are wondering, the world record for going without sleep is eleven days.) But __(12)__ that we sleep because we are tired is rather like stating that we eat because we are hungry – it is why we sleep, but not necessarily why we need it.
