Step-by-step explanation:
To transform sentences from the active to the passive voice, we must follow some simple steps. Let's use the first sentence in the question as a model:
"The woman buys the recycled items."
1. Find the subject of the sentence in the active voice. This subject will become the agent of the passive voice, preceded by the preposition "by": "the woman" --> "by the woman".
2. Identify the verb and its tense in the active voice. For the passive voice, we maintain the verb tense but add the auxiliary "be". In this case:
"buys" --> "is/are bought"
3. Find the object of the active voice. It becomes the subject of the passive voice: "the recycled items".
Therefore:
The recycled items are bought by the woman.
