How sleep helps the brain Scientists discovered that sleep plays a much more important role in our health than people previously thought. During the night, the brain did not simply rest — it worked actively to process the information that the person learned during the day. Researchers at a university in the United States carried out an experiment in 2019. They asked two groups of students to study a list of new words. The first group slept for eight hours after studying. The second group stayed awake all night. The next morning, the students who slept remembered 40% more words than the other group. The scientists also found that the brain cleaned itself during deep sleep by removing waste products that built up during the day. They concluded that getting enough sleep every night improved memory, concentration, and even mood. What did researchers ask the two groups of students to do? a) Take a memory test b) Study a list of new words c) Watch a video about the brain d) Write a short essay. a. b. c. d.

Why we yawn — and why it is contagious For many years, scientists believed that yawning happened because the body needed more oxygen. However, a series of experiments carried out in the 1980s showed that this idea was incorrect. Researchers discovered that people yawned just as often whether they breathed normal air or air with extra oxygen. A more recent theory suggested that yawning helped cool down the brain. When a person yawned, they took in cooler air, which lowered the temperature of the blood flowing to the brain. This helped the person stay alert. One of the most interesting aspects of yawning is that it is highly contagious. Scientists found that about 60% of people yawned after seeing someone else yawn — and some people even yawned just by reading about it. Researchers connected this contagious effect to empathy. People who scored higher on empathy tests were more likely to catch a yawn. Studies also showed that children under four years old and people with certain conditions that affect social awareness were less likely to experience contagious yawning. What did experiments in the 1980s prove about the old yawning theory? a) It was completely correct b) It needed more research c) It was incorrect d) It only applied to animals. a. b. c. d.

How elephants grieve their dead Elephants are among the few animals that show a strong emotional response to the death of another elephant. When a member of their group died, the other elephants gathered around the body. They touched it gently with their trunks and stood quietly nearby for hours. Scientists who observed this behavior concluded that elephants experienced something similar to grief. In one well-documented case in Kenya, a family of elephants returned to the same spot for three years after the death of their leader. They stopped, became quiet, and touched the bones that remained on the ground. Researchers noted that the elephants paid special attention to the skull and tusks. Interestingly, when scientists moved the bones to a different location, the elephants searched for them. Elephants also reacted strongly to the deaths of elephants they had never met. In experiments, they showed more interest in the bones of elephants than in the bones of other animals. This suggested that elephants recognized their own species even in death, which pointed to a level of self-awareness that was rare in the animal kingdom. How did elephants behave when a member of their group died? a) They left the area immediately b) They gathered around and touched the body c) They made loud sounds for days d) They covered the body with leaves. a. b. c. d.
