Wildlife campaigners have insisted that scientific evidence has proved that elephants in zoos don't breed well and suffer a wide range of health problems. On top of that, it's claimed they die at a younger age than those living in the wild or kept in parks. The government in Canberra is allowing these Asian elephants into Australia as part of a conservation program that it believes will help safeguard the species. The population of these magnificent animals has been reduced over the past century. It's estimated that fewer than 34,000 now remain across a dozen countries. What can we know about the elephants in zoos？ A．They generally breed well. B．They may not suffer health problems. C．They may die relatively young. D．They are cleverer than the wild elephants.

The 140 cities in the survey are judged on five broad categories:stability, healthcare, culture and environment, education and infrastructure. The top scorers tend to be mid-sized cities in wealthy countries with a low population density. Some seven of the top ten – including Vancouver, Toronto and Sydney – are in Australia or Canada. Vienna, Helsinki and Auckland also made the top ten. Of the cities surveyed – and some like Kabul and Baghdad were not included for safety reasons – Dhaka in Bangladesh was rated the least livable. Lagos, Harare, Algiers and Karachi all scored poorly as well. The city that has dropped fastest down the list in the last year is Damascus, due to the ongoing conflict in Syria, while infrastructure improvements in China mean that cities like Shanghai and Suzhou have scored better than they did last year. 31.
