Spur smb/sth (on) to something/to do something

[sondra]

Hello!

I would be grateful if you corrected the second and thrid sentences. The first sentence is taken from a book, and in the other two sentence the construction has been slightly changed. Thanks!

1.The professor spurred on by a bet with a friend, takes on the challenge of changing the flower girl's speech and manners to make her acceptable to upper-class London society.

2.The professor spurred on by a bet with a friend, to take on the challenge of changing the flower girl's speech and manners to make her acceptable to upper-class London society.

You could use was spurred on and remove the commas in both.

Professor Higgins would insist on a comma after the word "professor" in the quoted sentence.

"Sentences" 2 and 3 have no main verb.

Unless you change spurred into one.
