Explanation:

The Ballad of Songbird and Snakes is a novel written by Suzanne Collins. It is a backstory of the President of Panem, Coriolanus Snow.

The situation above happened when Coriolanus Snow entered the truck with the tributes in order to accompany Lucy Gray to the quarters. The truck was enclosed with metal bars and this confined the tributes inside. Upon reaching their destination, they were dumped down on a chute into a cold cement. Coriolanus thought that they were at the stables, but later on, he found out that they were in a monkey house at a zoo.
