That is correct- there is not meant to be a passage for this question. Instead, the point is to quiz you on what type of question the presented question stem indicates.
Here, the question stem is: "Which one of the following is the main point of the passage?" What type of question does this refer to? You'll see that (C) "Main Point" is the correct answer. Nothing about the hypothetical passage in reference was necessary to know to answer this.
Does that make sense? Please let us know if you have any other questions!
