Answer: "For an African, whether you were sent to the Caribbean or South America, you were now part of the sugar machine."
The excerpt explains that slaves were performing similar jobs, receiving similar punishments and enduring similar suffering regardless of the colony they arrived to. Most sugar plantations followed the same system to produce sugar, and it was equally brutal everywhere. Work had to be done constantly and quickly, and slaves were punished often. The sentence that best exemplifies this idea is the first one.
