What does the author actually mean when he describes Jethro Mann as being "head over wheels" in the introduction?
(A) Mann's Bicycle Lending Library has expanded to other cities because it is
(B)
Mann is enthusiastic about his ability to help others with his Bicycle
Lending Library.
(C)Mann's community service has earned him fame in North Carolina.
(D) Mann's bicycle repairing is the only way he help others in the community

(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 ''Head over Heels'' 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.

this doesnt make any sense imao
