Question

Which is a common problem with thesis statements?
They are too vague.
They are too specific.
They contain no textual evidence.
They are not included in the first sentence of the essay.

Answer 1

It can be both A and B. You certainly don't need textual evidence in the thesis statement since you provide evidence/details in your body paragraphs. The thesis statement doesn't need to be included in the first sentence in the essay. You should open your essay with a little background information, a small fact or story, a quote etc. before you write your thesis statement. So you can rule out C and D.

I'd narrow it down and say the answer is either A or B.

Answer 2

That's what I thought too. It can either be too narrow or too broad. What I think you should do is go back to the content you are reading and according to what is in the lesson, choose the answer that fits the most.
