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 youre 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.\ copyright 2011 by condé nast

Explanation:

The relevant part from the text is "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". This shows that sweet foods (indicated by sweetness as a sign of ripeness) are more likely to be safe and nutritious (good to eat) compared to bitter foods. The other part about the lesser mouse lemur adjusting its sweetness threshold is about how primates' taste for sugar varies, not about the safety/nutrition of sweet vs bitter foods.

Answer:

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
