Help! What revision, if any, is needed to make this thesis statement more effective?

In William Shakespeare's The Taming of the Shrew, Petruchio, with his ability to use language so skillfully, is far more successful at manipulating people than Lucentio.

a
It needs to address meaning, or the "so what?"

b
It needs to be arguable or defensible.

c
It should provide evidence for the position.

d
It should provide the last names of the characters.

e
No revision is needed; the thesis is effective.

Thank you!
