MCQ-> Read the following passage and answer the questions. Passage:The Chinese have been drinking tea for health and enjoyment for more than 5000 years. No one knows what drew them to the glossy, green leaves of Camellia sinensis, but a popular legend fills the gap in our knowledge. According to legend, ShenNong, an early emperor required that all drinking water be boiled. One summer day while visiting a distant region of his kingdom, he stopped to rest because he felt very tired. The servants began to boil water for the king and his ministers to drink. Dried leaves from a nearby bush fell into the boiling water, turning it into a brown liquid. The Emperor drank some of the new liquid. He felt fresh and much better after drinking the liquid. And thus, tea was created. According to an Indian legend a Buddhist monk, on one of his travels about 2000 years ago, swore not to sleep during the nine years of his journey. However, by the end of the third year, he was so fatigued he almost fell asleep. That is when he accidentally stumbled upon a wild tree and picked a few leaves from its top. He chewed on the leaves and soon recovered. Thanks to these leaves, he was able to stay awake during the next six years of his mission. The Japanese version of this legend is slightly different. The monk had vowed to meditate for 7 years without sleep. One night however, he fell asleep. He was so angry with himself that he cut off his eyelids and threw them to the ground. A few years later, passing by the same spot, he noticed a strange-looking bush. He tasted its leaves, and realized that they gave him the power to keep his eyes open. This story soon spread, and tea bushes are often seen in Buddhist places of worship.In all the three legends. the leaves help the person who eats it to recover. This suggests that the leaves :
