Originally Answered: An english teacher that gives a quote once a week. We have to interpret the quote. Is there a wrong answer?
If a quote is very old, the meaning has been agreed upon by scholars for decades, and if it's more recent, current literary scholars agree on the author's ideas. Students will have some variation on how they express an idea of course, but if you're far away from the interpretation that many literary scholars agree is correct, then the teacher can say you're wrong.
Thousands of people major in English literature each year, and most questions about any writers have been resolved and agreed upon by countless professors. This is one area of knowledge that seems open for discussion, and in fact it is not. You're free to disagree in your own mind, but not in class.
If you're being given quotes you don't know, you should ask your teacher to meet with you after class one day and ask her how you can better prepare for the weekly quotes interpretation. Maybe your teacher picks a quote that relates to topics your class has discussed, even in other subjects such as history.
