Question

Well, we cannot give you the answer. 

But, a thesis statement is basically your opinion + the topic 
A thesis is rather specific than vague or generalized sentence about a specific item (like a research paper or a story). 

Example of a weak Thesis Statement: The people of Mesopotamia learned how to control the Tigris River and invented the wheel.  

It is a weak Thesis Statement because you do not know whether the story/article is about inventing the wheel or the people controlling the Tigris River.
