Explanation:

"The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, The African" is the autobiography of a former slave Equiano. He narrated the events of his younger days and being captured as slaves, his life story of how he became a Christian, and then got his freedom after which he decided to work to free slaves.

In chapter II, Equiano described how the holding cell where they were 'stuffed' in onboard the ship was so "pestilential" that it became unbearable to even survive. Three conditions that made the hold in such a condition were the "filth of the tubs" which then made some of the slaves sick and eventually killed them. This added to the stench. And also, the "closeness of the place, and the heat of the climate, added to the number in the ship, which was so crowded that each had scarcely room to turn himself . . . produced copious perspirations" also added to the congested nature of the hold.
