Mateo has written this paragraph about the availability of flavored milk in schools. Which sentence needs more supporting details to help readers better understand it?

Offering students chocolate, vanilla, strawberry, and other sweetened milk beverages could be more harmful than helpful. If students consume more milk because they have more flavor choices, they will also consume more sugar. Some experts believe that students are less attentive in class and distracted because of the sugar rush that comes from drinking sweetened beverages. Furthermore, sugar consumption blocks the ability for calcium absorption to take place, which defeats the purpose of drinking milk to begin with—for the health benefits.
