The correct answer is D.

"What is the average income of a dentist in the United States?" is an appropiate question for research because it has only one possible answer. The average income can be calculated and through deep inquiring one can get the correct answer.

On the other hand, the rest of the questions may present different answers according to the person replying.

the answer that is correct is the last option.

answer: buck is a dog living a charmed life on the estate of judge miller, during the time of the klondike gold rush in 1897. he is the king of all the animals on the estate and as such enjoys special privileges, such as the run of the estate and the admirable position of being the judge's favorite dog.

this all ends the day he accompanies manuel on a walk through the orchard to a flag station, where manuel sells him to a stranger. manuel sells buck, because he has gambling debts he needs to pay and a family to support.

this one act changes buck's life irrevocably. it is the catalyst for the rest of the story about buck and his transformation from domestic pet to wild animal.
