AcademicWriting&CriticalThinking

1、单选题：
Read the following passage about Zoos and answer the questions.​​Zoos have existed in some form since at least 2500 BC in Egypt and Mesopotamia, where records indicate giraffes, bears, dolphins, and other animals were kept by aristocrats. The oldest still operating zoo in the world, Tiergarten Schönbrunn in Vienna, opened in 1752. Although controversy has historically surrounded zoos, from debates over displaying "exotic" humans in exhibits to zookeepers not knowing what to feed animals, I do believe that zoos should exist. ①In my opinion, zoos are important institutions that promote scientific research and public education, and save animals from extinction.​First of all, zoos produce helpful scientific research. Since so many diseases can be transmitted from animals to humans, such as Ebola and the bird flu, zoos frequently conduct disease surveillance research in wildlife populations and their own captive populations that can lead to a direct impact on human health. Take the zoos in the United Stated as an example. In 2017, 173 accredited US zoos spent $25 million on research, studied 485 species and subspecies of animals, worked on 1,280 research projects, and published 170 research manuscripts.​②Zoos can also educate the public about animals and conservation efforts. According to a study of 26 zoos worldwide published in Conservation Biology, visitors to zoos increased their knowledge of biodiversity and specific individual actions to protect biodiversity. Robin Ganzert, PhD, President and CEO of American Humane, once stated, "Zoos provide people, especially impressionable children, with the opportunity to see these remarkable animals up close. People won't protect what they don't love, and they can't love what they don't know.” ③It is zoos that give people the chance to appreciate the animals from different corners of the world in real life.​In addition, zoos help save species from extinction and other dangers. According to records, there were only nine California condors in the wild in 1985. ④However, a joint conservation effort between the San Diego and Los Angeles Zoos with other organizations resulted in a population of 276 California condors in the wild and another 170 in captivity by 2016. The truth is that zoos are working to save polar bears, tigers, and wild African elephants from habitat loss, apes and rhinos from poachers, dolphins and whales from hunters, and bees and butterflies from population declines, among many other efforts to help many other animals.​In conclusion, zoos do bring a lot of benefits to mankind and thus have a reason to exist. No matter in the promotion of scientific research and public education or in the save of animals from extinction, they have indeed made a huge difference.​ ​1. What is the main argument of the author?​
选项：
A: Zoos should exist.
B: Zoos help save species from extinction and other dangers.
C: Zoos can promote scientific research and public education, and save animals from extinction.
D: Zoos should exist because they can help promote scientific research and public education, and save animals from extinction.
答案: 【 Zoos should exist because they can help promote scientific research and public education, and save animals from extinction.】点我阅读全文
