Final answer:
The timeline supports the passage by providing historical context and supporting the central ideas with specific dates, emphasizing the evolution of sugar production and its socio-economic impacts.
Step-by-step explanation:
The timeline provided in the passage plays a crucial role in supporting the text by anchoring key developments in the history of sugar to specific dates, thus highlighting the evolution and the impact of sugar production and trade over time. It supports the central ideas of the passage by providing historical context, such as the discovery that beet sugar is identical to cane sugar, and the major milestones in the expansion of beet cultivation in Europe, which correlates with the narrative of innovation and serfdom found within the passage. The timeline also indirectly sheds light on the integral role of slavery in the sugar industry by outlining key dates in relation to serfdom and workforce transitions in global sugar production, thereby tying together the broader socio-economic effects of the sugar trade.
