hello everybody,
So, I've been searching for the passive forms verbs and all I knew is that passive verbs are always transitive verbs.
But, in some exercices it's requested to transform sentences from active to passive voice such as "six per cent of the eligible population are blood donors" .
The verb in this case is "to be" and it's intransitive, so how can I transform the sentence.
Waiting for your answers and Thanks
