Answer:
The active sentence "Sam had taken the medicines" can be changed to passive voice by following these steps:
1. Identify the subject of the active sentence. In this case, the subject is "Sam."
2. Move the subject to the end of the sentence and add the preposition "by" before it. The passive voice often uses "by" to indicate who performed the action. In this case, the passive sentence will start with "The medicines were taken."
3. Rewrite the verb in the active sentence ("had taken") as a past participle. In this case, the past participle of "take" is "taken."
4. Add the auxiliary verb "had" to the passive sentence, which matches the tense of the original sentence. The final passive sentence is "The medicines were taken by Sam."
So, the passive voice of the sentence "Sam had taken the medicines" is "The medicines were taken by Sam." In the passive voice, the focus is on the object ("medicines") rather than the subject ("Sam"), and the sentence emphasizes the action performed on the object.
