Answer:
Following the strand of sugar and slavery leads directly into the tumult of the Age of Revolutions.
Step-by-step explanation:
In the book, Sugar Changed the World by the writer couple Marc Aronson and Marina Budhos, the history of the spices that make up our daily lives is rediscovered and described in detail. Starting from the sugar plantations and into the lesser-known slave trade of these plantations, the authors brought to light the various circumstances that led to the discovery of sugar.
Slavery and sugar are connected by the very act of slavery which enables the production of the sweet spice. But sugar also acts as the link between slavery and freedom, forming the imaginary line between the two sides of the world. And the brutality of this trade is brought to the fore with the need to reform and change the condition and life of the people employed as slaves. This emphasis on the condition of the slaves and the most brutal form of slavery shows how it directly led to the tumult that is to come from the numerous Revolutions that will shake the world., which is what the authors' claim is.
Thus, the correct answer is the last option.
