Answer: It indicates that the addition of sugar was a significant change to Europeans' diets.
Step-by-step explanation: The first option is incoherent with the text because the concept of dessert as the sweet final course of a meal had not appeared yet.

It is only the final option that finds support throughout the text, especially in the last three sentences of it.
