Part B

11. Which quotation from the text best supports the answer in Part A?

• “The frog in Dr. Val’s hand is a Madagascar poison frog. It’s small, only about an inch (3 cm) long. Its mostly black body is decorated with splashes of bright green, orange, and yellow.” (paragraph 2)

• “Most frogs are nocturnal, which means they are awake at night. But mantella frogs are active during the day when hungry animals can see them. So they have a way to tell predators to stay away.” (paragraph 3)

• “The warning is no bluff. Mantella frogs ooze a poisonous liquid through their skin, like sticky sweat. In fact, many frogs can do this. Mantella frogs have enough toxin (poison) to smell and taste bad to predators.” (paragraph 4)

• “So what is it that makes these frogs taste so nasty? Where do their toxins come from? And why do some frogs have more poison than others? These are the mysteries Dr. Val and her friends are trying to solve.” (paragraph 5)

Which two quotations from the text support the author’s point that scientists have learned important information about mantella frogs?

• “Deep in a steamy rainforest, a researcher carefully holds a colorful frog. She searched for hours to find it, pushing her way through tangled undergrowth and combing through leaf litter.” (paragraph 1)

• “The frog in Dr. Val’s hand is a Madagascar poison frog. It’s small, only about an inch (3 cm) long.” (paragraph 2)

• “If it doesn’t smell too terrible, then she touches the tip of her tongue to the frog. Poisons taste very bitter. So she saves the worst-tasting frogs for closer study.” (paragraph 7)

• “Dr. Val and her team tested bad-tasting frogs from all around Madagascar. And what did they discover? More than 80 different kinds of bitter-tasting chemicals called alkaloids cover the frogs’ skin.” (paragraph 8)

• “Dr. Val’s team made another interesting discovery—frogs living far away from people are more poisonous than frogs that live near roads and farms.” (paragraph 12)
