The names of these twin male giant panda cubs were announced at Atlanta Zoo last year. Lun Lun, a 15-year-old giant panda, gave birth to the cubs on July 15, 2013. Zoo officials followed Chinese custom and named the brothers after waiting 100 days. Until then, they were simply known as "Cub A" and " Cub B". Mei Lun and Mei Huan are the first twin panda cubs to survive in the Unite States. "We're delighted to finally be able to place two youngsters with names. They have not only made a mark on the history of Atlanta Zoo, but also have made history in the US," Raymond B. King , the zoo's president and CEO, said in a statement. Atlanta Zoo teamed up with Good Morning America that month to put the pandas' names to a public vote. China's Chengdu Research Base of Giant Panda Breeding provided the choices of names. In just 13 days, 51,000 votes poured in on the show's website. Under a deal between China and the US, giant pandas originally from China are only lent to foreign zoos for scientific study for several years. Zookeepers at Atlanta Zoo are giving regular updates on the twins' progress in an online blog. Mei Lun and Mei Huan are the fourth and fifth offspring of Lun Lun and a male giant panda named Yang Yang. The pandas made their first public appearance in a US exhibit last fall. For the three months before their appearance, the online world had watched the twins grow strong and healthy. "We share this joy with our colleagues in China and with the cub's fans around the world," King said. Question: How did the twins get their names? Options: A: Good morning America named them. B: Zoo Atlanta gave them the names. C: China provided their names for votes. D: The US decided their names.

Read the article and select the best answer. Article: Members of an elephant family may be out of sight but they are always in the minds of the herd's matriarchs , researchers have found. Tests have found that female elephants are able to remember the whereabouts of at least 17 family members simultaneously and perhaps as many as 30. They watch which of their relations are ahead of them when the herd searches for food, which of them are lagging behind and which are traveling in separate groups. Professor Richard Byrne, of the prefix = st1 /UniversityofSt Andrews, said that the elephants performed a good memory by being able to recall where each of their s was in a changing environment. "It's hard enough for us to watch two or three children in a busy shopping centre. Imagine trying to do it with 30 or so," he said. Researchers tested the ability of African elephants to remember where each family member had got to. Elephants have poor eyesight but an excellent sense of smell and are able to identify one another from traces of urine on the ground. To test the memories of the elephants, samples of urine-soaked earth were collected by researchers and placed in positions where a herd was about to pass. Observations showed that the animals exhibited surprise when they could detect the odor of a family member they knew was behind them. Interest was shown when the urine was that of a close traveling in the same group or in a separate herd, but samples left by unknown individuals were ignored. The researchers, who reported their findings in the journal Biology Letters, concluded: " It seems that female elephants have a general interest in monitoring family members with whom they are traveling. Elephants' order of traveling often changes and overtaking is common, suggesting that elephants must frequently update their expectation of where others are in relation to themselves." Question: Elephants identify their family members mainly by using their_. Options: A: eyes B: nose C: ears D: mouth

Ques: Read the article and select the best answer. Article: Animals are a favorite subject of many photographers. Cats, dogs, and other pets top the list, followed by zoo animals. However, because it's hard to get them to sit still and "perform on command," some professional photographers refuse to photograph pets. One way to get an appealing portrait of a cat or dog is to hold a biscuit or treat above the camera. The animal's longing look toward the food will be captured by the camera, but the treat won't appear in the picture because it's out of the camera's range. When you show the picture to your friends afterwards, they'll be impressed by your pet's loving expression. If you are using fast film, you can take some good, quick shots of a pet by simply snapping a picture right after calling its name. You'll get a different expression from your pet using this technique. Depending on your pet's mood, the picture will capture an interested, curious expression or possibly a look of annoyance, especially if you've awakened it from a nap. Taking pictures of zoo animals requires a little more patience. After all, you can't wake up a lion! You may have to wait for a while until the animal does something interesting or moves into a position for you to get a good shot. When photographing zoo animals, don't get too close to the cages, and never tap on the glass or throw things between the bars of a cage. Concentrate on shooting some good pictures, and always respect the animals you are photographing. Question: What is the use of a biscuit in taking pictures of a pet? Options: A: To capture a cute look. B: To create a special atmosphere. C: To arouse the appetite of the pet. D: To keep the pet from looking at the camera.
Ans: A
