Different secondary works will often disagree in their constructions of the evidence, and it is up to you to decide which of them (if any) is more persuasive.
Papers in which you weigh the opposing positions and try to make your own judgment are often the most satisfying for both the student and the reader.
However, the topic you choose should have an obvious relationship to Judaism as it has been discussed in the course.
In particular, you should make sure that it relates to Judaism as a religion and not to other aspects of Jewish experience (e.g., historical, political, ethnic); and that it indeed relates to the post-biblical eras--including their understandings of biblical texts.
Note: If you find that your paper topic has become much narrower than what you originally expected, and that you are only dealing with a small portion of what you had intended to at the beginning, do not worry.
This is a sign that you are on the right track, and that you are learning more about the subject (which is, after all, one of the main purposes of the assignment).
In this section of the paper you provide the necessary historical and literary background for your chosen topic and develop the needed descriptive information and arguments in support of the task you have set for yourself in the introduction.
In other words, there should be a clear connection between what you have stated in the introduction as the purpose of the paper and what it is that you discuss in the text of the paper itself.
These are provided to give you ideas you might like to pursue.
You should not feel that you are confined to the topic areas on the list.
