• "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 they mysteries Dr. Val and her friends are trying to solve."

12. Why do scientists gather information about the bugs that live near mantella frogs?

• It helps scientists know what mantella frogs may eat.

• It helps scientists know how mantella frogs find food to eat.

• It helps scientists know when mantella frogs eat during the day.

• It helps scientists know why mantella frogs eat some foods but not others.

13. Which quotation 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."

• "The frog in Dr. Val's hand is a Madagascar poison frog. It's small, only about an inch long."

• "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."

• "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."

14. What text structure does the author use in the "You Are What You Eat" section?

• The author uses problem and solution to explain how mantella frogs are able to find enough food by eating bugs that other animals do no eat.

• The author uses compare and contrast to explain the similarities and differences between mantella frogs that live in the wild and those kept in captivity.

• The author uses chronological order to explain that mantella frogs found in the wild make less poison today that they did in the past.

• The author uses cause and effect to explain how the diet of mantella frogs impacts the amount of alkaloids in their body.

15. Which quotation support the inference that finding mantella frogs in the wild is challenging?

• "She searched for hours to find it, pushing her way through tangled undergrowth and combing through leaf litter. Sweat drips off her forehead."

• "The frog in Dr. Val's hand is a Madagascar poison frog. It's small, only about an inch long."

• "These are the mysteries Dr. Val and her friends are trying to solve. She has led two research teams to Madagascar to search for answers."

• "So she saves the worst-tasting frogs for closer study. She places frogs with little or no taste back where she found them."

16. This is the frogs' secret.

What does the author mean by the sentence in paragraph 11.

• Mantella frogs have a special way of making their own poison.

• Mantella frogs have a special way of hiding from predators.

17. How does the information in the additional text add to the information in the text "The Real Frog Princess"?

• The additional text explains that there are a number of different varieties of mantella frogs in Madagascar.

• The additional text provides information about another place where mantella frogs have been found by scientists.

• The additional text provides information about why mantella frogs may be going down in numbers in Madagascar.

• The additional text explains that the poison on the skin of mantella frogs may taste bad to predators.

18. How does the information in the text "The Real Frog Princess" compare to the information in the text "The Tiny Mantella Frog"?

• Both texts are firsthand accounts because they are written by people who are scientists studying the poisons made by mantella frogs.

• Both texts are secondhand accounts because they are written by people who researched mantella frogs and how they are studied by scientists.

• "The Real Frog Princess" includes a firsthand account from a scientist who explains the importance of saving mantella frogs, but "The Tiny Mantella Frog" is a secondhand account that describes why there are fewer mantella frogs in Madagascar.

• The Real Frog Princess" includes firsthand accounts from scientists who studied the different ways that the poisons of mantella frogs are tested, but "The Tiny Mantella Frog" is a secondhand account that explains why the poisons of mantella frogs are so dangerous.
