Article: Most cultures have a feast or festival of light. Each culture celebrates this festival in a different way. The Jewish Festival of Light is called Hanukkah. It usually takes place in December. The story of why Hanukkah is celebrated is very old. It is told that a long time ago, Jewish people called the Macabees were at war with a country called Syria. On the day that the Macabees won the war, they cleaned up their holy place, which is called a temple, because the Syrian people had been living there. They wanted to light their holy lamps to say thank you for the end of the year, but found only a very small amount of oil left over to do that. The Macabees lit the lamps anyway, thinking that they would soon go out. The lamps kept burning for eight days! The Jewish people celebrate Hanukkah every year by lighting a candlestick that has eight candleholders. Every night a new candle is lit so that on the eighth night, all eight candles stand together. Presents are given at this time and money is given to the poor. The Christmas story is not quite as old as the Hanukkah story, but it is also very old. Christmas is the time when Christians around the world celebrate the birth of Jesus Christ. It is believed that Christ was born in a stable. On the night of his birth, angels, shepherds and three wise men visited him. The wise men brought gifts with them. This is a happy and busy time of the year. Homes are decorated with Christmas trees and decorations. It is a time for being with the family. Families travel long distances to gather at Christmas. Lots of lights are put up everywhere. This is to show that Jesus is the"Light of the world"who came to bring peace to all people. Lanterns are another form of light. In China, the Lantern Festival goes back to the Han Dynasty. One emperor heard that Buddhist monks would light lanterns to _ Buddha on the 15th day of the 1st lunar month;so he also ordered to light lanterns in the imperial palace and temples to show respect to Buddha on the day. Later, the rite developed into a grand festival among common people. During the festival, parks become a sea of lanterns. Sometimes streets are blocked off and lanterns are put down on each side to make a hallway of lanterns. People also hang lanterns in their gardens, outside their houses or on boats. It is believed that the lanterns will guide visitors and the spirits of ancestors to the celebrations. The Lantern Festival is a time for families to reunite.

Article: A dog found shot in the head and face with a pellet gun, stuffed in a garbage bag and left to die is recovering from his injuries at an animal clinic in Texas. The bag containing the 3-year-old male mixed breed was discovered tied to a fence in Conroe, Texas, earlier this month. When local residents opened the bag, the dog appeared, took a few steps and fell. Augustyn rushed the dog to an emergency animal clinic, where he was treated for many pellets to the face, eyes, mouth, neck and shoulders. The dog was stabilized, but according to Dr Ron Hendrick, a vet at the Animal Emergency Clinic of Conroe, pellets remain in both eyes and it's unclear whether the dog nicknamed Buck was left blind forever. A Facebook page, Buck Needs Bucks for His Buckshot Injuries, was launched last week by Augustyn. It was created to help pay for the dog's medical bills. The page has attracted nearly 7,000 "likes" and, according to its creator, already more than enough donations to pay for his treatment. "The last 24 hours has been overwhelming for me," Augustyn wrote on the page. "I have gone from not knowing if I would have enough money to pay for Buck's emergency bill to having an unbelievable amount of money to provide the best possible care for Buck's recovery. I have thought long and hard about this today and how I should handle this. The conclusion is that I will open a separate bank account for Buck and all donations will be used for Buck's recovery and necessities." With the help of Facebook, Buck's story quickly sparked international interest. "Buck is now walking," Augustyn says. Police in Montgomery County say they are investigating the incident, and Augustyn says she has been in contact with law enforcement officials about donating a reward for information leading to the arrest of the person who tortured the dog. Sadly, cases like Buck's are not uncommon, particularly in Texas.
Question: When Augustyn found the dog, it was _ .
Options: (A) being shot by its owner (B) tied to a fence near an animal clinic (C) in a horrible physical state (D) hiding from its owner inside a bag

Article: The famous American gorilla expert Diane Fossey had a completely new way to study gorillas -- she pretended to be one of them. She copied their actions and way of life -- eating plants and getting down on her hands and knees to walk the way a gorilla does. It was a new relationship. Diane Fossey was murdered in Rwanda in 1985 and her story was made into the popular filmGorillas in the Mist. It was a long way fromKing Kong, which is about a gorilla as a monster (a frightening animal), and helped to show a new idea: the real monster is man, while the gorilla is to be admired. Today there are thought to be around 48,000 lowland gorillas and maybe 400--450 mountain gorillas in the wild. From the Congo in West Africa, to Rwanda and Uganda further east, they are endangered by hunting and by the cutting down of their forest homes. Some time ago, I found in my letterbox a little magazine from the World Wide Fund for Nature. It had two photos side by side. One was of a young gorilla. "This is a species of mammal ," said the words below it. "It is being destroyed by man. We must save it for our own good." The other photo showed a human baby. The words also read, "This is a species of mammal," but then went on: "It is the most destructive on earth. We must retrain it for its own good."
Question: The text mainly talks about _ .
Options: (A) Diane Fossey (B) the gorillas in Rwanda (C) the protection of the gorillas (D) the film Gorillas in the Mist
