resposta:Letra “c” - When children watch TV, a wide range of places, people, and information is encountered.

Note que na “Active Voice”, o núcleo do sujeito da oração é ‘range’. Então, por uma questão de concordância com “range“, que corresponde a “it”, a forma do verbo “to be” precisa ser “is” (is encountered).

a) can be taken

b) must be obeyed

c) was broken

Questão 4

a) She will be given a wedding ring. / A wedding ring will be given to her.

b) They were told the truth. / The truth was told to them.

c) Nina was showed his new books. / His new books were shown to Nina.

d) Iwlah was offered a new job. / A new job was offered to Iwlah.

e) I was sent a letter. / A letter was sent to me.

Essas são as possíveis frases que podem ser feitas na voz passiva. Na passiva, o verbo“ to be” assume o tempo do verbo da voz ativa; logo, se na voz ativa o verbo possui dois objetos, qualquer um deles pode ser sujeito da passiva: I gave him a shirt → A shirt was givem to him → He was given a shirt (by me).
