Teacher: In this task, you are given a sentence and a profession. The sentence mentions two professions: one's gender is identifiable using the coreference link with gendered pronouns and the other's gender is unidentifiable. You are expected to return whether the given profession's gender is identifiable or unidentifiable.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Sentence: The cleaner called the guard because she forgot to bring her key.
 Profession: cleaner
Solution: Identifiable
Reason: The cleaner's gender is identifiable because the pronoun "she" is linked to the cleaner.

Now, solve this instance: Sentence: The developer refused to take a book from the librarian because he liked the internet better than books.
 Profession: librarian
Student:
Unidentifiable
