Raoul works for the public utilities department of a city, and he's currently researching rainwater harvesting techniques. he borrowed a book on
the topic from the library to use as a source in his research. how should he credit the source in his writing?
a. he should email the publisher of the book to get quotes on the topic.
b. he should mention the title of the book in his writing.
c. he should list the book as a source on his reference page.
d. he should call the author to ask permission to use the book.

Answer is Option C: He should list the book as a source on his reference page.

Explanation:

When we use a book for reference for our writing, we always list the book as source in our references page. We sue these materials to support our points. Since Raoul used a book from the library to use a source in his research, he should list the book in his reference page as a source.

He doesn't need to email the publisher of the book as per Option A. Nor should he mention the title of the book in his writing as option B. He also doesn't need to call the author for permission as per Option D.

the words “strangest” and “unusual” suggest that the narrator is about to tell the story of an odd or puzzling group of people.
