Thesis

1. A is the weaker thesis statement. It is short and not specific enough. It covers a very ambiguous topic whereas the latter one is more defined and focused.
2. Again, A is the more ambiguous and therefore weaker. The latter explains where the paper is going, whereas the first does not.
3. For once, B is the weaker thesis. It is unfocused, where A is more direct in where the paper will head.
4. A is the weaker thesis. Othello is more than just a play about love and jealousy, the first thesis does not get that point across. The second one says what the first one says, yet expounds on it and explains further.
5. A is the weaker of the two. It does not stay focused and is more than one sentence long. The second sentence says almost the same thing in a much more composed manner.
