The part of a textbook that states the author's purpose is the Preface/Introduction.
B.............................................
Answer: (B) Mann is enthusiastic about his ability to help others with his Bicycle Lending Library.
Explanation:
I am unsure as to which book or text this refers to but the phrase ''<em>Head over Heels</em>'' is used to describe a person who is very much in love with or enthusiastic about something. For instance, ''Mark is head over heels for badminton'' means that Mark really love badminton.
In using the phrase ''head over wheels'', the author is making a play on the phrase to describe that Mann is enthusiastic about something bicycle related so the option that he is enthusiastic about his ability to help others with his Bicycle Lending Library must be right.
Any dark word that can make the reader feel.
