Which sentence is correct? Please help

Neither one of them is correct.

Well, can you please suggest a correct form?

Thanks for your reply.

You might write: "What generates a sense of humor, and how?"--however, a native speaker would not say that, either. The verb most likely be used with the locution "a sense of humor" would likely be develop. "How does one develop a sense of humor?"

Thank you very much.
