But the user's example shows exactly that. The sample input has two words with variations: use and point. The sample output has three versions, each using the first, second, and third variants respectively. So first version: action and point; second: motion and stage; third: use and moment. So each version cycles through the same index for all bracketed words.

So each variant is used once. So the task is to generate three versions of the sentence where each place with v1 takes one variant per version. So for each variation, pick the first variant for one case, the second for another, etc. Like, for the first sentence, first variation uses all first options, second variation uses second options, etc.

"see it in action at this point see it in motion at this stage see it in use at this moment"

Therefore, the user's task is to take the input text with v3 and produce three lines as per the replacement rules.

Each sentence takes the same index from each group.
