One day, when an Ant was nimbly running about in search of food, came across a Chrysalis that was close to its time of change. The Chrysalis moved its tail, and thus attracted the attention of the Ant, who then saw for the first time that it was alive. “Poor, pitiable animal!” cried the Ant disdainfully. “What a sad fate is yours! While I can run hither and hither, at my pleasure, and, if I wish, ascend the tallest tree, you lie imprisoned here in your shell, with power only to move a joint or two or your scaly tail.” The Chrysalis heard all this but did not try to make any reply. A few days after, when the Ant passed that way again, nothing but the shell remained. Wondering what had become of its contents, he felt himself suddenly shaded and fanned by the gorgeous wings of a beautiful Butterfly, “Behold in me, your much pitied friend!” said the Butterfly, “Boast of your powers to run and climb as long as you can get me to listen now” So saying, the Butterfly rose in the air, and, borne along and aloft on the summer breeze, was soon lost to the sight of the Ant forever. What is the text mostly about? A. The Ant and the Chrysalis. B. The Beautiful Butterfly. C. The Chrysalis shell. D. The Powerful Ant.

Batu Belah Batu Betangkup In ancient times, in a small village in Indragiri Hilir lived a widow named Mak Minah with her three children. The first child was named Diang, a woman. While the other two were men, each named Utuh and Ucin. To fulfill the living needs of her three children, Mak Minah must always work. Mak Minah's job was selling firewood to the market. The three Mak Minah children are very naughty. They did not want to listen to Mak Minah's advice. The three of them often refute orders from their mother. They just like to play around, even late at night. Mak Minah often felt sad about her children's behaviour. He often prayed for his children to be aware and willing to respect their parents. The next day Mak Minah prepared a lot of food for her children. After that he went to the river and approached a rock while talking. The stone can also open and then close again, like a conch. People often call it a cup of stone "O Batangkup Stone, swallow me. I can no longer live with my three children who have never respected their parents, "said Mak Minah. The rock was then swallowed up by Mak Minah's body, so that what was left of Mak Minah's body was only part of her hair. By late afternoon, his three children began to feel surprised. They have not seen their mother since morning. However, because there is enough food, they end up just eating and then playing again. After the second day, the food began to run out. Mak Minah's children start to get confused and feel hungry. Until the night they were confused looking for his mother. It was only the next day after they went to the bank of the river, they found the end of Mak Minah's hair that was unraveled swallowed by a thick rock. "O Batangkup Stone, we need our mother. Please remove our mother from your stomach, "they wailed. "No!!! You only need Mother when you are hungry. You have never loved and respected Mother, "answered Batu Batangkup. They continued to mourn and cry "We promise to help, love and respect Mother," they promised. Eventually the stone was granted the three Mak Minah children's lamentations. Mak Minah was removed from the cupped stone. They also became diligent in helping their mothers and loved Mak Minah. However, this did not last long. Sometime later they change the nature back to normal. Like playing around and lazy to help parents. Mak Minah was sad again. He then visited and then sat on a river bank. He was then swallowed up again by the stone. Mak Minah's children are still busy playing around. By late afternoon, then they realize that their mother does not exist anymore. They returned to visit the stone-shaped bowl on the bank of the river while lamenting that their mother's stone was removed by the stone-shaped cup. However, this time the cup stones are already angry. He then said, "You guys are bad kids. Your regret this time is useless, "said the stone Batubatungkup as he swallowed them. Batangkup stone has entered the ground and until now has never reappeared. Sometime later they change the nature back to normal. The underlined word refers to… A. Mak Minah B. Batu Batungkup C. Utuh and Ucin D. Mak Minah’s children
