Devon is writing a report about keeping dogs happy and healthy. He will collect information about dogs' health from many different sources. One will be an interview with a dog walker. The dog walker would NOT be the correct source to answer which of these questions?

C) What type of dog food has the best nutrition for dogs?

Explanation:

Writing a report about how to keep dogs happy and healthy will require not only the collection of information about the animal's health but also even an individual interview with whoever is responsible for the well-being of that animal. And in interviewing the dog walker, Devon is focusing on one source among many others.

Now, regarding questions asked to a dog walker, it will be within a certain limit that the dog walker will be able to provide questions. One question that he/she cannot provide the answer for will be the type of dog food that provides the best nutrition. Since he/she is just a dog walker, he/she will be responsible for the outdoor walks and runs, and not for the food that is given to the dog.

Thus, the correct answer is option C.
