Just like the Olympics, the Rio 2016 Paralympic Games faced issues heading into competition, but those issues will move to the background as the opening ceremony begins on Wednesday night.
The Paralympics feature 4,300 athletes from 161 nations and a team comprised of refugee athletes.
The organizers suffered financial problems heading into the games, as International Paralympic Committee president Philip Craven said that he was notified about five weeks ago by the Rio Olympic organizing committee that there was no money left to run the Paralympics.
