Final answer:
To convert the sentence 'The police didn't find any evidence' into past simple passive, the sentence is changed to 'Any evidence wasn't found by the police'. The correct options are A and C.
Step-by-step explanation:
The provided sentence 'The police didn't find any evidence' is already in past simple active form. In this sentence, the doer of the action (in this case, 'the police') is active in the sentence structure. However, you are asked to change it to the past simple passive form. In passive constructions, the focus is on the action and not on who or what is performing the action.
Therefore, by converting the sentence into the past simple passive voice the sentence becomes: 'Any evidence wasn't found by the police'. Here, the object in the original sentence ('any evidence') becomes the subject in the passive sentence and the original subject ('the police') is now introduced by 'by' in the passive sentence. Thus, the correct option out of the given four is option A and C as they both have the sentence 'Any evidence wasn't found by the police'.
