Bonjour,
Réponse :
a. When he presented his social network website, everybody wondered where Rupert Murdoch had got the strange idea from.
Quand il a présenté son site... tout le monde s'est demandé d"où il avait eu cette étrannge idée..
==> il a présenté son site au même moment où tout le monde s'est demandé = prétérit. Par contre, son étrange idée, Rupert Murdoch l'a eue avant = past perfect
b. Benjamin Suresh had decided to return home a long time before, but when he came back, he hardly recognised his native country.
c. The month after India became independent, many Indians came back as they had always planned.
d. Regular CD buyers wondered why Tower Records shop had closed down.
e. The Queen took the news that India was independent calmly as everybody had expected her to.
Explications :
Past perfect = had + participe passé
( attention à la place des adverbes )
On dit que c'est du passé dans le passé. Dans chaque phrase, il faut retrouver ce qui a eu lieu avant ( c'est ce que l'on doit mettre au past perfect )
