Given the task definition, example input & output, solve the new input case.
In this task, you are given two sentences in Persian separated with <sep>, and you have to determine whether the sentences are paraphrases or not. Classify your answers into "paraphrase" and "not-paraphrase".
Example: اگر Apple ID و ایمیل خود را فراموش کرده ام چه کاری می توانم انجام دهم؟ <sep> Apple ID و رمز عبور خود را فراموش کردم ، چه کاری باید انجام دهم؟
Output: not-paraphrase
This is a good example. The first sentence is about forgetting email, and the second one is about forgetting the password, so they are not paraphrases.

New input case for you: چرا به امام سجاد زین العابدین می گفتند کلاس سوم؟ <sep> چرا به امام سجاد علیه السلام زین العابدین می گفتند؟
Output:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
