A cautious and optimistic stance should be adopted while trying to understand the situation in a positive manner.
Answer: C) Poison dart frogs are brightly colored and poisonous to animals that eat them.
A is not the answer because that line explains where frogs get their names from, and introduces the topic of bright colors talking about the frog's bright eyes. B links the topic of bright colors to the fact that they serve as a warning sign for poison or danger, and D supports this topic by stating that bright colors help red-eyed tree frogs survive in nature. C, on the other hand, introduces a new species of frog that is not talked about during the rest of the essay, and it does not support the idea of colors being crucial in the red-eyed tree frog's surivival.
Answer: Grandpa: 60 Granddaughter: 6
Explanation: When I first saw this, I noticed you can not get one solid whole number with a number like 54, so I rounded it up to 60, because 10 percent of 60 is 6. It IS possible for someone to be 5.4, but with age, not a lot of people care to go down to the decimal point. I then checked the other part. 60 IS 54 years more than 6, so 60 is correct.
