Question

Ritter states that space technology that seemed futuristic in the 1950s has long since been invented (16). What does the number 16 refer to?

Answer 1

If you had attached some options to choose I would definitely have helped you and give the correct answer. Even though this excerpt looks like a  paragraph 16 in the research paper but I am pretty sure that the right answer is page 16 of a book by author Ritter. Because the number at the end always indicates a page number on which the quote can be found. Do hope you still need the answer because this one is really helpful.
