Пояснение:

Артикль a / an ставится перед исчисляемым существительным в единственном числе, когда говорится о профессии:

• a teacher

• an architect

• a doctor

• an actor

An употребляется перед словами, которые начинаются с гласного звука:

• an architect

• an anesthetist

• an actor

Если существительное стоит во множественном числе, артикль не нужен:

• they are teachers

• are doctors

• want to be artists

Слово hospital здесь в единственном числе, поэтому нужно:

• in a hospital

Итоговый вариант целиком:

a) This is Dan and this is Nicola. They are teachers. And this is Bob. He is not a teacher. He is an architect.

b) My father and mother are doctors and they work in a hospital. My father is a cardiologist and my mother is an anesthetist. I don't want to be a doctor, I want to be an actor. And my two sisters don't want to be doctors. They want to be artists.
