Estou em dúvida na resolução de dois exercícios que utilizam 'pronomes relativos'.
1) Use 'who, that, which or why' to combine the sentences below:
a) The church was destroyed by the fire. The church was rebuilt by the community.
b) Who was that boy? The boy was waiting outside.
2) Describe each situation below using 'when, where, that, which, why or who'
Exemplo: a day when you made a very important decision.
Resposta: I made a very important decision when I chose my major
a) when you were when you met someone very special.
b) a person who had a great influence on you as a child.
c) a time when you had to choose between two important things/people.
Sei que essa número 2 é pessoal, mas mesmo assim não estou sabendo como colocar o pronome.
Queria me ajudassem por favor, e se possível explicar.
Agradeço desde já.
