Question

select the best evidence to support the statement that in nature, sweet foods are more likely to be safe and nutritious than bitter foods. primates, i learned, love sweets for reasons that are simple enough to explain: sweetness is the natural sign of ripeness, and the best assurance, especially when balanced with just enough acids, that the thing you’re eating is good to eat. yet the picture is more complex. the primate instinct for sugar is particular, adjustable, and sometimes seasonal. the lesser mouse lemur of madagascar, a gourmand among monkeys, raises its threshold during the rainy season so that, when sugars are less abundant, it requires less sweetness. from adam gopnik, \sweet revolution.\

Explanation:

The relevant text states that sweetness in nature (like in ripe foods) is a sign of being good to eat, and primates' instinct for sugar (relating to sweet foods) ties to this. This supports that sweet foods (due to ripeness signaled by sweetness) are more likely safe/nutritious. The part about primates loving sweets because sweetness signals ripeness and edibility is the best evidence.

Answer:

The text: "sweetness is the natural sign of ripeness, and the best assurance, especially when balanced with just enough acids, that the thing you’re eating is good to eat" (from the primates - related explanation)
