•  Read the story “The Starfruit Tree”and answer the questions. (1 point)

  Once there was a rich man living in a village. When he died, he left his two sons a fortune. But the elder brother gave his younger brother only a starfruit tree. When the fruit was ripe, an eagle came and ate the fruit. The younger brother asked the eagle not to. The eagle promised to repay him in gold and told him to make a bag to carry it. The eagle took him on its back to a place of gold. There, he filled the bag with gold. When he got home he was rich. The elder brother was surprised, so he asked his brother to explain. After hearing the story, he offered to swap his fortune for the starfruit tree, and his kind brother agreed. When the eagle came, the elder brother asked it to take him to the place of gold. The greedy brother filled a very large bag and all his pockets with gold. On the way home, because the load was too heavy, the eagle got tired and dropped him into the sea. 

  What did the elder brother give his younger brother?

• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.     

  Different cultures follow their own special customs when a child's baby teeth fall out.

  In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses. Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog. The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!The phrase "the wee hours" in paragraph 3 probably refers to the period of time ______.
