The following exercise asks you to identify the pronoun corresponding to a noun whose gender, number and case is clearly indicated by an article/demonstrative.
The pronoun you select should match the noun and its article/demonstrative in gender and number, but the case of the pronoun will be determined by its role in its own clause (nominative subject, accusative object, dative object, genitive possessor, etc.).
If your first try is incorrect, you will be given 4 possible choices for the answer. Keep trying until you get the right answer, at which point you will be given some comments and presented with the next question.
