Choose the correct passive voice transformation of the sentence:
He claimed to have seen a rare species of bird during his expedition to the Amazon rainforest.
Show answer & explanation
Correct answer: B
Explanation
To transform the sentence 'He claimed to have seen a rare species of bird during his expedition to the Amazon rainforest' into the passive voice, the focus must shift from the subject ('He') to the object of the claim ('A rare species of bird').
The correct transformation requires placing the object of the infinitive phrase 'to have seen' at the beginning of the sentence, followed by the passive construction of the main verb ('was claimed') and the passive infinitive phrase (“to have been seen”).
