Identification v. Categorisation

The questions in this exercise all use the copula, but some use the identification construction (identifying who the subject is) and some the categorisation construction (stating what category of things/people the subject belongs to), so the answers will be different. Note:

A) You can answer a categorisation question with Is ea or Ní hea.
"An mac léinn thú?" "Is ea."

B) To answer a definite type, you must use the appropriate pronoun. E.g.:
"An í an múinteoir í?" "Ní hí."

Choose the correct answer to each question.
