Answer:
Dependent
Explanation:
Use of while makes the clause dependent on the occasion which will occur next.
1. It was already one in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out, when, by the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs.
-Personification is shown in this excerpt, specifically in the line "I saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs." Because the author is giving human like characteristics to the light.
2. Mingled with this horror, I felt the bitterness of disappointment; dreams that had been my food and pleasant rest for so long a space were now become a hell to me; and the change was so rapid, the overthrow so complete!
- The line "for so long a space were now become a hell to me; and the change was so rapid, the overthrow so complete" uses a metaphor because the vents that take place aren't literally hell, but they are describing it in a way that makes it feels that way.
The window had 5 panes of glass.

I would say that this excerpt is used <span>to reveal the horrors of enslavement. It seems that Cugoano described the scene with some many details for the reader to be able to actually picture what was happening, the horror suffered and how it might affect any person in that place. It was not just him suffering but there were others who he could listen to, they were also crying. </span>
