One of the [largest / longest]   circus companies in the USA will soon no longer have performing elephants [as / was]   part of its shows. The Ringling Brothers and Barnum & Bailey Circus said it would stop [useful / using]   elephants by 2018. All the 43 animals it [currently / currency]   uses will be moved to an animal [conversation / conservation]   centre in Florida. There, the giant creatures will live [in / out]   their retirement. The decision [came / come]   after a lot of protests from the public. One hundred years ago, people thought it was OK for animals to perform to [thank / please]   humans. However, the world is different today and people are more [worried / worrying]   about the lives of the animals. The circus will continue to use other animals, [like / such]   as camels, dogs, horses, lions and tigers. Circuses have been criticised for many years [by / at]   animal rights activists and the public who care [around / about]   the treatment of animals. Jessica Johnson, a spokeswoman for PETA (People for the [Unethical / Ethical]   Treatment of Animals) explained [how / when]   elephants have a bad life in circuses. She said:  "Many of the elephants are [painful / painfully]   arthritic, and many have tuberculosis, so their retirement day needs to [coming / come]   now." Many cities and towns in the USA have [banned / binned]   the use of elephants for entertainment. This has made it hard [by / for]   circuses to travel around the country. Owners of the circus company said the decision to stop using elephants was [not / non]   easy but understood that: "There's been somewhat of a mood shift [between / among]   our consumers."
