okay is this a better thesis?

Question

Minnie Wright’s insanity relates to isolation, unhappy marriage and the gender difference all causes her to the murder of her husband.

Answer 1

You've still simply stated the facts of the story. No opinion here.

A true thesis statement includes factual information plus your opinion or the position you take regarding that factual information.

So ... what's your OPINION about what Minnie Wright did?
Is your opinion something all the other readers of the story would agree with? If so, ditch it and write another. You want an opinion or position that you have to support -- to convince others that you are right, no matter what they thought at first.

fact + opinion = thesis
