In a subject-by-subject comparison essay, the thesis statement should be located in

In the introduction paragraph 

The correct answer is the introductory paragraph.

This is the paragraph that establishes what the essay would be about and contains a hook to make the readers want to read it. Putting it in body paragraphs would mean that it only applies to that subject while in reality you want to present the problem, that is the thesis, and then examine it on a subject-by-subject basis.

The points for are used for asking questions, so for example let’s say you have a question that’s really urgent the point scale gives you up to 100 points.. not saying you always need to give 100 points but that’s what they are used for. also answering others questions will give you points.
